Also, non-root users can 1477349Sgshapiro no longer send out-of-band signals. Problem reported by 1577349Sgshapiro Michal Zalewski of BindView. 1677349Sgshapiro If LogLevel is greater than 9 and SASL fails to negotiate an 1777349Sgshapiro encryption layer, avoid core dump logging the encryption 1877349Sgshapiro strength. Problem noted by Miroslav Zubcic of Crol. 1977349Sgshapiro If a server offers "AUTH=" and "AUTH " and the list of mechanisms is 2077349Sgshapiro different in those two lines, sendmail might not have 2177349Sgshapiro recognized (and used) all of the offered mechanisms. 2277349Sgshapiro Fix an IP address lookup problem on Solaris 2.0 - 2.3. Patch 2377349Sgshapiro from Kenji Miyake. 2477349Sgshapiro This time, really don't use the .. directory when expanding 2577349Sgshapiro QueueDirectory wildcards. 2677349Sgshapiro If a process is interrupted while closing a map, don't try to close 2777349Sgshapiro the same map again while exiting. 2877349Sgshapiro Allow local mailers (F=l) to contact remote hosts (e.g., via 2977349Sgshapiro LMTP). Problem noted by Norbert Klasen of the University 3077349Sgshapiro of Tuebingen. 3177349Sgshapiro If Timeout.QueueReturn was set to a value less the time it took 3277349Sgshapiro to write a new queue file (e.g., 0 seconds), the bounce 3377349Sgshapiro message would be lost. Problem noted by Lorraine L Goff of 3477349Sgshapiro Oklahoma State University. 3577349Sgshapiro Pass map argument vector into map rewriting engine for the regex 3677349Sgshapiro and prog map types. Problem noted by Stephen Gildea of 3777349Sgshapiro InTouch Systems, Inc. 3877349Sgshapiro When closing an LDAP map due to a temporary error, close all of the 3977349Sgshapiro other LDAP maps which share the original map's connection 4077349Sgshapiro to the LDAP server. Patch from Victor Duchovni of 4177349Sgshapiro Morgan Stanley. 4277349Sgshapiro To detect changes of NDBM aliases files check the timestamp of the 4377349Sgshapiro .pag file instead of the .dir file. Problem noted by Neil 4477349Sgshapiro Rickert of Northern Illinois University. 4577349Sgshapiro Don't treat temporary hesiod lookup failures as permanent. Patch 4677349Sgshapiro from Werner Wiethege. 4777349Sgshapiro If ClientPortOptions is set, make sure to create the outgoing socket 4877349Sgshapiro with the family set in that option. Patch from Sean Farley. 4977349Sgshapiro Avoid a segmentation fault trying to dereference a NULL pointer 5077349Sgshapiro when logging a MaxHopCount exceeded error with an empty 5177349Sgshapiro recipient list.

This would 9973188Sgshapiro usually cause mail to be queued up and delivered later on. 10073188Sgshapiro Ignore F=z (LMTP) mailer flag if $u is given in the mailer A= 10173188Sgshapiro equate. Problem noted by Motonori Nakamura of Kyoto 10273188Sgshapiro University. 10373188Sgshapiro Work around broken accept() implementations which only partially 10473188Sgshapiro fill in the peer address if the socket is closed before 10573188Sgshapiro accept() completes. 10673188Sgshapiro Return an SMTP "421" temporary failure if the data file can't be 10773188Sgshapiro opened where the "354" reply would normally be given. 10873188Sgshapiro Prevent a CPU loop in trying to expand a macro which doesn't exist 10973188Sgshapiro in a queue run. Problem noted by Gordon Lack of Glaxo 11073188Sgshapiro Wellcome. 11173188Sgshapiro If delivering via a program and that program exits with EX_TEMPFAIL, 11273188Sgshapiro note that fact for the mailq display instead of just showing 11373188Sgshapiro "Deferred". Problem noted by Motonori Nakamura of Kyoto 11473188Sgshapiro University. 11573188Sgshapiro If doing canonification via /etc/hosts, try both the fully 11673188Sgshapiro qualified hostname as well as the first portion of the 11773188Sgshapiro hostname. Problem noted by David Bremner of the 11873188Sgshapiro University of New Brunswick. 11973188Sgshapiro Portability: 12073188Sgshapiro Fix a compilation problem for mail.local and rmail if SFIO 12173188Sgshapiro is in use.

Miller of Courtesan Consulting. 12873188Sgshapiro Unixware 7.1.1 doesn't allow h_errno to be set directly if 12973188Sgshapiro sendmail is being compiled with -kthread. Problem 13073188Sgshapiro noted by Orion Poplawski of CQG, Inc. 13173188Sgshapiro CONTRIB: buildvirtuser: Substitute current domain for $DOMAIN and 13273188Sgshapiro current left hand side for $LHS in virtuser files. 13373188Sgshapiro DEVTOOLS: Do not pass make targets to recursive Build invocations. 13473188Sgshapiro Problem noted by Jeff Bronson of J.D. Bronson, Inc. 13573188Sgshapiro MAIL.LOCAL: In LMTP mode, do not return errors regarding problems 13673188Sgshapiro storing the temporary message file until after the remote 13773188Sgshapiro side has sent the final DATA termination dot. Problem 13873188Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic 13973188Sgshapiro Institute. 14073188Sgshapiro MAIL.LOCAL: If LMTP mode is set, give a temporary error if users 14173188Sgshapiro are also specified on the command line. Patch from 14273188Sgshapiro Motonori Nakamura of Kyoto University. 14373188Sgshapiro PRALIASES: Skip over AliasFile specifications which aren't based on 14473188Sgshapiro database files (i.e., only show dbm, hash, and btree). 14573188Sgshapiro Renamed Files: 14673188Sgshapiro devtools/OS/OSF1.V5.0 => devtools/OS/OSF1.V5.x 14773188Sgshapiro 14871345Sgshapiro8.11.2/8.11.2 2000/12/29 14971345Sgshapiro Prevent a segmentation fault when trying to set a class in 15071345Sgshapiro address test mode due to a negative array index. Audit 15171345Sgshapiro other array indexing. This bug is not believed to be 15271345Sgshapiro exploitable. Noted by Michal Zalewski of the "Internet for 15371345Sgshapiro Schools" project (IdS). 15471345Sgshapiro Add an FFR (for future release) to drop privileges when using 15571345Sgshapiro address test mode. This will be turned on in 8.12. It can 15671345Sgshapiro be enabled by compiling with: 15771345Sgshapiro APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS') 15871345Sgshapiro in your devtools/Site/site.config.m4 file.

Problem noted by Jeff Earickson of 16571345Sgshapiro Colby College. 16671345Sgshapiro Don't issue DSNs for addresses which use the NOTIFY parameter (per 16771345Sgshapiro RFC 1891) but don't have FAILURE as value. 16871345Sgshapiro Initialize Cyrus-SASL library before the SMTP daemon is started. 16971345Sgshapiro This implies that every change to SASL related files requires 17071345Sgshapiro a restart of the daemon, e.g., Sendmail.conf, new SASL 17171345Sgshapiro mechanisms (in form of shared libraries). 17271345Sgshapiro Properly set the STARTTLS related macros during a queue run for 17371345Sgshapiro a cached connection. Bug reported by Michael Kellen of 17471345Sgshapiro NxNetworks, Inc. 17571345Sgshapiro Log the server name in relay= for ruleset tls_server instead of the 17671345Sgshapiro client name. 17771345Sgshapiro Include original length of bad field/header when reporting 17871345Sgshapiro MaxMimeHeaderLength problems. Requested by Ulrich Windl of 17971345Sgshapiro the Universitat Regensburg. 18071345Sgshapiro Fix delivery to set-user-ID files that are expanded from aliases in 18171345Sgshapiro DeliveryMode queue.

Patch from 19371345Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 19471345Sgshapiro Fix return values for IRIX nsd map. From Kari Hurtta of the Finnish 19571345Sgshapiro Meteorological Institute. 19671345Sgshapiro Fix parsing of DaemonPortOptions and ClientPortOptions. Read all 19771345Sgshapiro of the parameters to find Family= setting before trying to 19871345Sgshapiro interpret Addr= and Port=. Problem noted by Valdis 19971345Sgshapiro Kletnieks of Virginia Tech. 20071345Sgshapiro When delivering to a file directly from an alias, do not call 20171345Sgshapiro initgroups(); instead use the DefaultUser group information. 20271345Sgshapiro Problem noted by Marc Schaefer of ALPHANET NF. 20371345Sgshapiro RunAsUser now overrides the ownership of the control socket, if 20471345Sgshapiro created. Otherwise, sendmail can not remove it upon 20571345Sgshapiro close. Problem noted by Werner Wiethege. 20671345Sgshapiro Fix ConnectionRateThrottle counting as the option is the number of 20771345Sgshapiro overall connections, not the number of connections per 20871345Sgshapiro socket. A future version may change this to per socket 20971345Sgshapiro counting. 21071345Sgshapiro Portability: 21171345Sgshapiro Clean up libsmdb so it functions properly on platforms 21271345Sgshapiro where sizeof(u_int32_t) != sizeof(size_t). Problem 21371345Sgshapiro noted by Rein Tollevik of Basefarm AS. 21471345Sgshapiro Fix man page formatting for compatibility with Solaris' 21571345Sgshapiro whatis.

Problem noted by Motonori Nakamura 25071345Sgshapiro of Kyoto University. 25171345Sgshapiro RMAIL: Undo the 8.11.1 change to use -G when calling sendmail. It 25271345Sgshapiro causes some changes in behavior and may break rmail for 25371345Sgshapiro installations where sendmail is actually a wrapper to 25471345Sgshapiro another MTA. The change will re-appear in a future 25571345Sgshapiro version. 25671345Sgshapiro SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X, 25771345Sgshapiro and SunOS 5.8.

Fix from John Beck of Sun Microsystems. 27066494Sgshapiro Don't try STARTTLS in the client if the PRNG has not been properly 27166494Sgshapiro seeded. This problem only occurs on systems without 27266494Sgshapiro /dev/urandom. Problem detected by Jan Krueger of 27366494Sgshapiro digitalanswers communications consulting gmbh and 27466494Sgshapiro Neil Rickert of Northern Illinois University. 27566494Sgshapiro Don't use the . and .. directories when expanding QueueDirectory 27666494Sgshapiro wildcards. 27766494Sgshapiro Do not try to cache LDAP connections across processes as a parent 27866494Sgshapiro process may close the connection before the child process 27966494Sgshapiro has completed. Problem noted by Lai Yiu Fai of the Hong 28066494Sgshapiro Kong University of Science and Technology and Wolfgang 28166494Sgshapiro Hottgenroth of UUNET. 28266494Sgshapiro Use Timeout.fileopen to limit the amount of time spent trying to 28366494Sgshapiro read the LDAP secret from a file. 28466494Sgshapiro Prevent SIGTERM from removing a command line submitted item after 28566494Sgshapiro the user submits the message and before the first delivery 28666494Sgshapiro attempt completes. Problem noted by Max France of AlphaNet. 28766494Sgshapiro Fix from Neil Rickert of Northern Illinois University. 28866494Sgshapiro Deal correctly with MaxMessageSize restriction if message size is 28971345Sgshapiro greater than 2^31. Problem noted by Tim "Darth Dice" Bosserman 29071345Sgshapiro of EarthLink. 29166494Sgshapiro Turn off queue checkpointing if CheckpointInterval is set to zero. 29266494Sgshapiro Treat an empty home directory (from getpw*() or $HOME) as 29366494Sgshapiro non-existent instead of treating it as /.

Suggested by 32966494Sgshapiro Henrik Nordstrom of Ericsson. 33066494Sgshapiro On HP-UX 10.X and 11.X, use /usr/sbin/sendmail instead of 33166494Sgshapiro /usr/lib/sendmail for rmail and vacation. From 33266494Sgshapiro Jeff A. Earickson of Colby College. 33366494Sgshapiro On HP-UX 11.X, use /usr/sbin instead of /usr/libexec (which 33466494Sgshapiro does not exist). From Jeff A. Earickson of Colby 33566494Sgshapiro College. 33666494Sgshapiro Avoid using the UCB subsystem on NCR MP-RAS 3.x. From 33766494Sgshapiro Tom Moore of NCR. 33866494Sgshapiro NeXT 3.X and 4.X installs man pages in /usr/man. From 33966494Sgshapiro Hisanori Gogota of NTT/InterCommunicationCenter. 34066494Sgshapiro Solaris 8 and later include /var/run. The default PID file 34166494Sgshapiro location is now /var/run/sendmail.pid. From John 34266494Sgshapiro Beck of Sun Microsystems. 34366494Sgshapiro SFIO includes snprintf() for those operating systems 34466494Sgshapiro which do not. From Todd C. Miller of Courtesan 34566494Sgshapiro Consulting. 34666494Sgshapiro CONFIG: Use the result of _CERT_REGEX_SUBJECT_ not {cert_subject}. 34766494Sgshapiro Problem noted by Kaspar Brand of futureLab AG. 34866494Sgshapiro CONFIG: Change 553 SMTP reply code to 501 to avoid problems with 34966494Sgshapiro errors in the MAIL address. 35066494Sgshapiro CONFIG: Fix FEATURE(nouucp) usage in example .mc files.

This more closely 35666494Sgshapiro matches pre-8.10 nullclient behavior. From Per Hedeland of 35766494Sgshapiro Ericsson. 35866494Sgshapiro CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for 35966494Sgshapiro SMTP to all *smtp* mailers and those for RELAY to the relay 36066494Sgshapiro mailer as described in cf/README. 36166494Sgshapiro MAIL.LOCAL: Open the mailbox as the recipient not root so quotas 36266494Sgshapiro are obeyed. Problem noted by Damian Kuczynski of NIK. 36366494Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 36466494Sgshapiro makemap to 'unmake' the map. 36566494Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 36666494Sgshapiro sendmail. 36766494Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 36866494Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 36966494Sgshapiro Meteorological Institute. 37066494Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 37166494Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 37266494Sgshapiro dot as the only character on the line. 37366494Sgshapiro New Files: 37466494Sgshapiro cf/ostype/solaris8.m4 37566494Sgshapiro 37664562Sgshapiro8.11.0/8.11.0 2000/07/19 37764562Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 37864562Sgshapiro (not the normal case), some operating systems will still 37964562Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 38064562Sgshapiro to drop all of its privileges. If sendmail needs to drop 38164562Sgshapiro these privileges and the operating system doesn't set the 38264562Sgshapiro saved-uid as well, exit with an error. Problem noted by 38364562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 38464562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 38564562Sgshapiro it populates. It is possible that some broken 38664562Sgshapiro implementations of snprintf() exist that do not do this. 38764562Sgshapiro Systems in this category should compile with 38864562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 38964562Sgshapiro system and report broken implementations to 39064562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 39164562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 39264562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 39364562Sgshapiro Implementation influenced by the example programs of 39464562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 39564562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 39664562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 39764562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 39864562Sgshapiro cf/README and doc/op/op.*. 39964562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 40064562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 40164562Sgshapiro ${server_name}, and ${server_addr}. These are documented 40264562Sgshapiro in cf/README and doc/op/op.*. 40364562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 40464562Sgshapiro random data. 40564562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 40664562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 40764562Sgshapiro try to use STARTTLS despite the security problems. 40864562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 40964562Sgshapiro support encryption. Based on code contributed by Tim 41064562Sgshapiro Martin of CMU. 41164562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 41264562Sgshapiro strength factor. 41364562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 41464562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 41564562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 41664562Sgshapiro of CMU. 41764562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 41864562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 41964562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 42064562Sgshapiro Fix the default family selection for DaemonPortOptions. As 42164562Sgshapiro documented, unless a family is specified in a 42264562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 42364562Sgshapiro also the default if no DaemonPortOptions value is set. 42464562Sgshapiro Therefore, IPv6 users should configure additional sockets 42564562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 42664562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 42764562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 42864562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 42964562Sgshapiro the interface information for an outgoing connection. 43064562Sgshapiro Not doing so was creating a mismatch between the socket 43164562Sgshapiro family and address used in subsequent connections if the 43264562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 43364562Sgshapiro by John Beck of Sun Microsystems. 43464562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 43564562Sgshapiro family based on the IP address. ${if_family} is no longer 43664562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 43764562Sgshapiro of Sun Microsystems. 43864562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 43964562Sgshapiro macros for both the incoming interface address/family and 44064562Sgshapiro the outgoing interface address/family. In order for M=b 44164562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 44264562Sgshapiro the incoming information in the queue file for later 44364562Sgshapiro delivery attempts. 44464562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 44564562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 44664562Sgshapiro smoe.org. 44764562Sgshapiro Add more vigilance in checking for putc() errors on output streams 44864562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 44964562Sgshapiro noted by Graeme Hewson of Oracle. 45064562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 45164562Sgshapiro Problem noted by Ajay Matia. 45264562Sgshapiro Under certain circumstances, an address could be listed as deferred 45364562Sgshapiro but would be bounced back to the sender as failed to be 45464562Sgshapiro delivered when it really should have been queued. Problem 45564562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 45664562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 45764562Sgshapiro the SMTP transaction out of sync. Problem noted by Per 45864562Sgshapiro Hedeland of Ericsson. 45964562Sgshapiro Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT 46064562Sgshapiro is defined to avoid a core dump due to incompatibilities 46164562Sgshapiro between sfio and stdio. Problem noted by Neil Rickert 46264562Sgshapiro of Northern Illinois University. 46364562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 46464562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 46564562Sgshapiro Convert the free disk space shown in a control socket status query 46664562Sgshapiro to kilobyte units. 46764562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 46864562Sgshapiro looking up the hostname, requeue the message for a later 46964562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 47064562Sgshapiro Polytechnic. 47164562Sgshapiro Under the proper circumstances, failed connections would be recorded 47264562Sgshapiro as "Bad file number" instead of "Connection failed" in the 47364562Sgshapiro queue file and persistent host status. Problem noted by 47464562Sgshapiro Graeme Hewson of Oracle. 47564562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 47664562Sgshapiro within the hoststatus directory (e.g., lost+found). 47764562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 47864562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 47964562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 48064562Sgshapiro If a message data file can't be opened at delivery time, panic and 48164562Sgshapiro abort the attempt instead of delivering a message that 48264562Sgshapiro states "<<< No Message Collected >>>". 48364562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 48464562Sgshapiro restrictive. Problem noted by Mark G. Thomas of Mark 48564562Sgshapiro G. Thomas Consulting. 48664562Sgshapiro Preserve source port number instead of replacing it with the ident 48764562Sgshapiro port number (113). 48864562Sgshapiro Document the queue status characters in the mailq man page. 48964562Sgshapiro Suggested by Ulrich Windl of the Universitat Regensburg. 49064562Sgshapiro Process queued items in which none of the recipient addresses have 49164562Sgshapiro host portions (or there are no recipients). Problem noted 49264562Sgshapiro by Valdis Kletnieks of Virginia Tech. 49364562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 49464562Sgshapiro only the first to open the connection is allowed to close 49564562Sgshapiro it so a later map close doesn't break the connection for 49664562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 49764562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 49864562Sgshapiro authentication. Patch from Rainer Schoepf of the 49964562Sgshapiro University of Mainz. 50064562Sgshapiro Provide workaround for inconsistent handling of data passed 50164562Sgshapiro via callbacks to Cyrus SASL prior to version 1.5.23. 50264562Sgshapiro Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile.

Problem noted by Valdis Kletnieks of 69064562Sgshapiro Virginia Tech. 69164562Sgshapiro DEVTOOLS: configure.sh was overriding the user's choice for 69264562Sgshapiro confNROFF. Problem noted by Glenn A. Malling of Syracuse 69364562Sgshapiro University. 69464562Sgshapiro DEVTOOLS: New variables conf_prog_LIB_POST and confBLDVARIANT added 69564562Sgshapiro for other internal projects but included in the open source 69664562Sgshapiro release. 69764562Sgshapiro LIBSMDB: Check for ".db" instead of simply "db" at the end of the 69864562Sgshapiro map name to determine whether or not to add the extension. 69964562Sgshapiro This fixes makemap when building the userdb file. Problem 70064562Sgshapiro noted by Andrew J Cole of the University of Leeds. 70164562Sgshapiro LIBSMDB: Allow a database to be opened for updating and created if 70264562Sgshapiro it doesn't already exist. Problem noted by Rand Wacker of 70364562Sgshapiro Sendmail. 70464562Sgshapiro LIBSMDB: If type is SMDB_TYPE_DEFAULT and both NEWDB and NDBM are 70564562Sgshapiro available, fall back to NDBM if NEWDB open fails. This 70664562Sgshapiro fixes praliases. Patch from John Beck of Sun Microsystems. 70764562Sgshapiro LIBSMUTIL: safefile()'s SFF_NOTEXCL check was being misinterpreted 70864562Sgshapiro as SFF_NOWRFILES. 70964562Sgshapiro OP.ME: Clarify some issues regarding mailer flags. Suggested by 71064562Sgshapiro Martin Mokrejs of The Charles University and Neil Rickert of 71164562Sgshapiro Northern Illinois University. 71264562Sgshapiro PRALIASES: Restore 8.9.X functionality of being able to search for 71364562Sgshapiro particular keys in a database by specifying the keys on the 71464562Sgshapiro command line.

Problem noted by Michal Zalewski of the 75264562Sgshapiro "Internet for Schools" project (IdS). 75364562Sgshapiro SECURITY: There is a potential for a denial of service attack if 75464562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 75564562Sgshapiro sendmail process while it is rebuilding the aliases file 75664562Sgshapiro (leaving it in an inconsistent state). This option and 75764562Sgshapiro its use is deprecated and will be removed from a future 75864562Sgshapiro version of sendmail. 75964562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 76064562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 76164562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 76264562Sgshapiro (IdS). 76364562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 76464562Sgshapiro a large number of files. See cf/README for more details. 76564562Sgshapiro The directory structure of the distribution has changed slightly 76664562Sgshapiro for easier code sharing among the programs. 76764562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 76864562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 76964562Sgshapiro which hold the client's authentication credentials, 77064562Sgshapiro the mechanism used for authentication, and the 77164562Sgshapiro authorization identity (i.e., the AUTH= parameter if 77264562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 77364562Sgshapiro On systems which use the Torek stdio library (all of the BSD 77464562Sgshapiro distributions), use memory-buffered files to reduce 77564562Sgshapiro file system overhead by not creating temporary files on 77664562Sgshapiro disk. Contributed by Exactis.com, Inc. 77764562Sgshapiro New option DataFileBufferSize to control the maximum size of a 77864562Sgshapiro memory-buffered data (df) file before a disk-based file is 77964562Sgshapiro used. Contributed by Exactis.com, Inc. 78064562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 78164562Sgshapiro memory-buffered transcript (xf) file before a disk-based 78264562Sgshapiro file is used. Contributed by Exactis.com, Inc. 78364562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 78464562Sgshapiro now listen on several different ports. Use: 78564562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 78664562Sgshapiro to run a Message Submission Agent (MSA); this is turned 78764562Sgshapiro on by default in m4-generated .cf files; it can be turned 78864562Sgshapiro off with FEATURE(`no_default_msa'). 78964562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 79064562Sgshapiro begin using RFC 2476 Message Submission for initial user 79164562Sgshapiro message submission. XUSR may disappear from a future release. 79264562Sgshapiro The new '-G' (relay (gateway) submission) command line option 79364562Sgshapiro indicates that the message being submitted from the command 79464562Sgshapiro line is for relaying, not initial submission. This means 79564562Sgshapiro the message will be rejected if the addresses are not fully 79664562Sgshapiro qualified and no canonicalization will be done. Future 79764562Sgshapiro releases may even reject improperly formed messages. 79864562Sgshapiro The '-U' (initial user submission) command line option is 79964562Sgshapiro deprecated and may be removed from a future release. 80064562Sgshapiro Mail user agents should begin using '-G' to indicate that 80164562Sgshapiro this is a relay submission (the inverse of -U). 80264562Sgshapiro The next release of sendmail will assume that any message submitted 80364562Sgshapiro from the command line is an initial user submission and act 80464562Sgshapiro accordingly. 80564562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 80664562Sgshapiro program or deliver to file as the owner of that file, the 80764562Sgshapiro address is marked as unsafe. This means if RunAsUser is 80864562Sgshapiro set, users won't be able to use programs or delivery to 80964562Sgshapiro files in their .forward files. Administrators can override 81064562Sgshapiro this by setting the DontBlameSendmail option to the new 81164562Sgshapiro setting NonRootSafeAddr. 81264562Sgshapiro Allow group or world writable directories if the sticky bit is set 81364562Sgshapiro on the directory and DontBlameSendmail is set to 81464562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 81564562Sgshapiro InCert Software. 81664562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 81764562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 81864562Sgshapiro set in the DontBlameSendmail option. Requested by many. 81964562Sgshapiro New Timeout.control option to limit the total time spent satisfying 82064562Sgshapiro a control socket request. 82164562Sgshapiro New Timeout.resolver options for controlling BIND resolver 82264562Sgshapiro settings: 82364562Sgshapiro Timeout.resolver.retrans 82464562Sgshapiro Sets the resolver's retransmission time interval (in 82564562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 82664562Sgshapiro and Timeout.resolver.retrans.normal. 82764562Sgshapiro Timeout.resolver.retrans.first 82864562Sgshapiro Sets the resolver's retransmission time interval (in 82964562Sgshapiro seconds) for the first attempt to deliver a message. 83064562Sgshapiro Timeout.resolver.retrans.normal 83164562Sgshapiro Sets the resolver's retransmission time interval (in 83264562Sgshapiro seconds) for all resolver lookups except the first 83364562Sgshapiro delivery attempt. 83464562Sgshapiro Timeout.resolver.retry 83564562Sgshapiro Sets the number of times to retransmit a resolver 83664562Sgshapiro query. Sets both Timeout.resolver.retry.first 83764562Sgshapiro and Timeout.resolver.retry.normal. 83864562Sgshapiro Timeout.resolver.retry.first 83964562Sgshapiro Sets the number of times to retransmit a resolver 84064562Sgshapiro query for the first attempt to deliver a message. 84164562Sgshapiro Timeout.resolver.retry.normal 84264562Sgshapiro Sets the number of times to retransmit a resolver 84364562Sgshapiro query for all resolver lookups except the first 84464562Sgshapiro delivery attempt. 84564562Sgshapiro Contributed by Exactis.com, Inc. 84664562Sgshapiro Support multiple queue directories. To use multiple queues, supply 84764562Sgshapiro a QueueDirectory option value ending with an asterisk. For 84864562Sgshapiro example, /var/spool/mqueue/q* will use all of the 84964562Sgshapiro directories or symbolic links to directories beginning with 85064562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 85164562Sgshapiro mind, the queue directory structure should not be changed 85264562Sgshapiro while sendmail is running. Queue runs create a separate 85364562Sgshapiro process for running each queue unless the verbose flag is 85464562Sgshapiro given on a non-daemon queue run. New items are randomly 85564562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 85664562Sgshapiro Support different directories for qf, df, and xf queue files; if 85764562Sgshapiro subdirectories or symbolic links to directories of those names 85864562Sgshapiro exist in the queue directories, they are used for the 85964562Sgshapiro corresponding queue files. Keep in mind, the queue 86064562Sgshapiro directory structure should not be changed while sendmail is 86164562Sgshapiro running. Proposed by Mathias Koerber of Singapore 86264562Sgshapiro Telecommunications Ltd. 86364562Sgshapiro New queue file naming system which uses a filename guaranteed to be 86464562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 86564562Sgshapiro without fancy file system locking. Queued items can be 86664562Sgshapiro moved between queues easily. Contributed by Exactis.com, 86764562Sgshapiro Inc. 86864562Sgshapiro Messages which are undeliverable due to temporary address failures 86964562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 87064562Sgshapiro set. Contributed by Exactis.com, Inc. 87164562Sgshapiro New command line option '-L tag' which sets the identifier used for 87264562Sgshapiro syslog. Contributed by Exactis.com, Inc. 87364562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 87464562Sgshapiro avoids opening and reading each queue file when preparing 87564562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 87664562Sgshapiro Shared memory counters and microtimers functionality has been 87764562Sgshapiro donated by Exactis.com, Inc. 87864562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 87964562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 88064562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 88164562Sgshapiro being added. Suggested by Michael K. Sanders. 88264562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 88364562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 88464562Sgshapiro and John Beck of Sun Microsystems. 88564562Sgshapiro In low-disk space situations, where sendmail would previously refuse 88664562Sgshapiro connections, still accept them, but only allow ETRN commands. 88764562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 88864562Sgshapiro Ltd. 88964562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 89064562Sgshapiro on systems which support them. This can be used with LMTP 89164562Sgshapiro local delivery agents which listen on a named socket. An 89264562Sgshapiro example mailer might be: 89364562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 89464562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 89564562Sgshapiro A=FILE /var/run/lmtpd 89664562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 89764562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 89864562Sgshapiro instead. 89964562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 90064562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 90164562Sgshapiro connections), IPC (which will be deprecated in a future 90264562Sgshapiro version), and FILE (for UNIX domain socket delivery). 90364562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 90464562Sgshapiro flags. 90564562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 90664562Sgshapiro body of the original message on delivery status 90764562Sgshapiro notifications. 90864562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 90964562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 91064562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 91164562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 91264562Sgshapiro Steve Schweinhart of America Online. 91364562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 91464562Sgshapiro not be set after rulesets are defined. Suggested by 91564562Sgshapiro Mitchell Blank Jr of Exec-PC. 91664562Sgshapiro Do not report temporary failure on delivery to files. In 91764562Sgshapiro interactive delivery mode, this would result in two SMTP 91864562Sgshapiro responses after the DATA command. Problem noted by 91964562Sgshapiro Nik Conwell of Boston University. 92064562Sgshapiro Check file close when mailing to files.

Fix from Raj Kunjithapadam of 92664562Sgshapiro @Home Network. 92764562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 92864562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 92964562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 93064562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 93164562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 93264562Sgshapiro similar to check_rcpt etc. 93364562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 93464562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 93564562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 93664562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 93764562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 93864562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 93964562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 94064562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 94164562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 94264562Sgshapiro the corresponding DSN parameter values. Proposed by 94364562Sgshapiro Mathias Herberts. 94464562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 94564562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 94664562Sgshapiro before the message has been collected, thereafter it holds 94764562Sgshapiro the message size as computed by sendmail (and can be used 94864562Sgshapiro in check_compat). 94964562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 95064562Sgshapiro sendmail is using instead of the value of the DeliveryMode 95164562Sgshapiro option. 95264562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 95364562Sgshapiro Drop explicit From: if same as what would be generated only if it is 95464562Sgshapiro a local address.

Mongiovi of Georgia Tech. 95764562Sgshapiro Log "low on disk space" only when necessary. 95864562Sgshapiro New macro ${load_avg} can be used to check the current load average. 95964562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 96064562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 96164562Sgshapiro is set. 96264562Sgshapiro Flag -S for maps to specify the character which is substituted 96364562Sgshapiro for spaces (instead of the default given by O BlankSub). 96464562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 96564562Sgshapiro This flag is set by default for the host map. Based on a 96664562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 96764562Sgshapiro Open maps only on demand, not at startup. 96864562Sgshapiro Log warning about unsupported IP address families. 96964562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 97064562Sgshapiro of the sum of all headers. This can be used to prevent 97164562Sgshapiro a denial-of-service attack. 97264562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 97364562Sgshapiro headers and parameters within those headers. This option 97464562Sgshapiro is intended to protect mail user agents from buffer 97564562Sgshapiro overflow attacks. 97664562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 97764562Sgshapiro alias recursion. 97864562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 97964562Sgshapiro Map type syslog to log the key via syslogd. 98064562Sgshapiro Entries in the alias file can be continued by putting a backslash 98164562Sgshapiro directly before the newline. 98264562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 98364562Sgshapiro dead.letter file, formerly hardcoded to 98464562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 98564562Sgshapiro default), sendmail will not attempt to save to a 98664562Sgshapiro system-wide dead.letter file if it can not bounce the mail 98764562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 98864562Sgshapiro file as it has in the past when the dead.letter file 98964562Sgshapiro could not be opened. 99064562Sgshapiro New option PidFile to define the location of the pid file. The 99164562Sgshapiro value of this option is macro expanded. 99264562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 99364562Sgshapiro process title shown in 'ps' listings. 99464562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 99564562Sgshapiro (along with the already existing macros): 99664562Sgshapiro ${daemon_info} Daemon information, e.g. 99764562Sgshapiro SMTP+queueing@00:30:00 99864562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 99964562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 100064562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 100164562Sgshapiro ${daemon_port} Daemon port, e.g., 25 100264562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 100364562Sgshapiro New macros especially for virtual hosting: 100464562Sgshapiro ${if_name} hostname of interface of incoming connection. 100564562Sgshapiro ${if_addr} address of interface of incoming connection. 100664562Sgshapiro The latter is only set if the interface does not belong to the 100764562Sgshapiro loopback net. 100864562Sgshapiro If a message being accepted via a method other than SMTP and 100964562Sgshapiro would be rejected by a header check, do not send the message. 101064562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 101164562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 101264562Sgshapiro Provide header value as quoted string in the macro 101364562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 101464562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 101564562Sgshapiro The length of the header value is stored in ${hdrlen}. 101664562Sgshapiro H*: allows to specify a default ruleset for header checks. This 101764562Sgshapiro ruleset will only be called if the individual header does 101864562Sgshapiro not have its own ruleset assigned. Suggested by Jan 101964562Sgshapiro Krueger of Unix-AG of University of Hannover. 102064562Sgshapiro The name of the header field stored in ${hdr_name}. 102164562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 102264562Sgshapiro removed if the config file version is greater than or equal 102364562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 102464562Sgshapiro input "token (1)" but does not match "token". 102564562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 102664562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 102764562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 102864562Sgshapiro Ericsson. 102964562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 103064562Sgshapiro messages with 8-bit text in headers. Problem noted by 103164562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 103264562Sgshapiro of Ericsson. 103364562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 103464562Sgshapiro modified database map file. Problem noted by Chris Adams 103564562Sgshapiro of Renaissance Internet Services. 103664562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 103764562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 103864562Sgshapiro queue up the message instead of bouncing it. 103964562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 104064562Sgshapiro standard does not provide any indication of what to do when 104164562Sgshapiro something other than 250 is received. Based on a patch 104264562Sgshapiro from Steve Schweinhart of America Online. 104364562Sgshapiro New option TrustedUser allows to specify a user who can own 104464562Sgshapiro important files instead of root. This requires HASFCHOWN. 104564562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 104664562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 104764562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 104864562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 104964562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 105064562Sgshapiro $? tests also whether the macro is non-null. 105164562Sgshapiro Print an error message if a mailer definition contains an invalid 105264562Sgshapiro equate name. 105364562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 105464562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 105564562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 105664562Sgshapiro mailer to return after sending all data to it. 105764562Sgshapiro Only free memory from the process list when adding a new process 105864562Sgshapiro into a previously filled slot. Previously, the memory was 105964562Sgshapiro freed at removal time. Since removal can happen in a 106064562Sgshapiro signal handler, this may leave the memory map in an 106164562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 106264562Sgshapiro David Cooley of Colby College. 106364562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 106464562Sgshapiro local users in the passwd file. The UserDB code has 106564562Sgshapiro already decided the message will be passed to another host 106664562Sgshapiro for processing. Fix from Tony Landells of Burdett 106764562Sgshapiro Buckeridge Young Limited. 106864562Sgshapiro Support LDAP authorization via either a file containing the 106964562Sgshapiro password or Kerberos V4 using the new map options 107064562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 107164562Sgshapiro distinguished_name is who to login as. The method can be 107264562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 107364562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 107464562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 107564562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 107664562Sgshapiro of Stanford University. 107764562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 107864562Sgshapiro deprecated and will be removed in a future version. 107964562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 108064562Sgshapiro and the map has the column delimiter set, it turns that 108164562Sgshapiro response into a delimiter separated string. The LDAP map 108264562Sgshapiro will traverse multiple entries as well. LDAP alias maps 108364562Sgshapiro automatically set the column delimiter to the comma. 108464562Sgshapiro Based on patch from Booker Bense of Stanford University and 108564562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 108664562Sgshapiro Support return of multiple values for a single LDAP lookup. The 108764562Sgshapiro values to be returned should be in a comma separated string. 108864562Sgshapiro For example, `-v "email,emailother"'. Patch from 108964562Sgshapiro Curtis W. Hillegas of Princeton University. 109064562Sgshapiro Allow the use of LDAP for alias maps. 109164562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 109264562Sgshapiro attributes found in the match will be returned. 109364562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 109464562Sgshapiro breaking up a single entry into multiple entries. This is 109564562Sgshapiro needed for LDAP alias file specifications to allow for 109664562Sgshapiro comma separated key and value strings. 109764562Sgshapiro Keep connections to LDAP server open instead of opening and closing 109864562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 109964562Sgshapiro connections such that multiple maps which use the same 110064562Sgshapiro host, port, bind DN, and authentication will only result in 110164562Sgshapiro a single connection to that host. 110264562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 110364562Sgshapiro Be more careful about checking for errors and freeing memory on 110464562Sgshapiro LDAP lookups. 110564562Sgshapiro Use asynchronous LDAP searches to save memory and network 110664562Sgshapiro resources. 110764562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 110864562Sgshapiro Increase portability to the Netscape LDAP libraries. 110964562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 111064562Sgshapiro replaced with the literal contents of the map lookup key -- 111164562Sgshapiro note that this means a lookup can be done using the LDAP 111264562Sgshapiro special characters. The new '%0' token can be used instead 111364562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 111464562Sgshapiro For example, if the LDAP map specification contains '-k 111564562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 111664562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 111764562Sgshapiro user attribute. Instead, if the LDAP map specification 111864562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 111964562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 112064562Sgshapiro with the name "*". 112164562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 112264562Sgshapiro more than one is returned, it is equivalent to no records 112364562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 112464562Sgshapiro alias dereference option; "-Z size" limits the number of 112564562Sgshapiro matches to return. 112664562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 112764562Sgshapiro LDAP maps. The value should only contain LDAP specific 112864562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 112964562Sgshapiro settings will be used for all LDAP maps unless they are 113064562Sgshapiro specified in the individual map specification ('K' 113164562Sgshapiro command). This option should be set before any LDAP maps 113264562Sgshapiro are defined. 113364562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 113464562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 113564562Sgshapiro Tech. 113664562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 113764562Sgshapiro particular, class entries get much smaller, which can be 113864562Sgshapiro important if you have large classes. 113964562Sgshapiro On network-related temporary failures, record the hostname which 114064562Sgshapiro gave error in the queued status message. Requested by 114164562Sgshapiro Ulrich Windl of the Universitat Regensburg. 114264562Sgshapiro Add new F=% mailer flag to allow for a store and forward 114364562Sgshapiro configuration. Mailers which have this flag will not attempt 114471345Sgshapiro delivery on initial receipt of a message or on queue runs 114564562Sgshapiro unless the queued message is selected using one of the 114664562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 114764562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 114864562Sgshapiro New option ControlSocketName which, when set, creates a daemon 114964562Sgshapiro control socket. This socket allows an external program to 115064562Sgshapiro control and query status from the running sendmail daemon 115164562Sgshapiro via a named socket, similar to the ctlinnd interface to the 115264562Sgshapiro INN news server. Access to this interface is controlled by 115364562Sgshapiro the UNIX file permissions on the named socket on most UNIX 115464562Sgshapiro systems (see sendmail/README for more information). An 115564562Sgshapiro example control program is provided as contrib/smcontrol.pl. 115664562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 115764562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 115864562Sgshapiro number of processors online on the system (if that can be 115964562Sgshapiro determined). For single processor machines, this change 116064562Sgshapiro has no effect. 116164562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 116264562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 116364562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 116464562Sgshapiro Motonori Nakamura of Kyoto University. 116564562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 116664562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 116764562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 116864562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 116964562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 117064562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 117164562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 117264562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 117364562Sgshapiro connection-based denial of service attacks. 117464562Sgshapiro Log basic information about authenticated connections at LogLevel 117564562Sgshapiro 10 or higher. 117664562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 117764562Sgshapiro information (from= syslog line). 117864562Sgshapiro Log the DSN code for each recipient if one is available as a new 117964562Sgshapiro equate (dsn=). 118064562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 118164562Sgshapiro New "ph" map for performing ph queries in rulesets.

Contributed by Mark 118471345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 118564562Sgshapiro Detect temporary lookup failures in the host map if looking up a 118664562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 118764562Sgshapiro Finnish Meteorological Institute. 118864562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 118964562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 119064562Sgshapiro When a forward file points to an alias which runs a program, run 119164562Sgshapiro the program as the default user and the default group, not 119264562Sgshapiro the forward file user. This change also assures the 119364562Sgshapiro :include: directives in aliases are also processed using 119464562Sgshapiro the default user and group. Problem noted by Sergiu 119564562Sgshapiro Popovici of DNT Romania. 119664562Sgshapiro Prevent attempts to save a dead.letter file for a user with 119764562Sgshapiro no home directory (/no/such/directory). Problem noted by 119864562Sgshapiro Michael Brown of Finnigan FT/MS. 119964562Sgshapiro Include message delay and number of tries when logging that a 120064562Sgshapiro message has been completely delivered (LogLevel of 10 or 120164562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 120264562Sgshapiro Log the sender of a message even if none of the recipients were 120364562Sgshapiro accepted. If some of the recipients were rejected, it is 120464562Sgshapiro helpful to know the sender of the message. 120564562Sgshapiro Check the root directory (/) when checking a path for safety. 120664562Sgshapiro Problem noted by John Beck of Sun Microsystems. 120764562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 120864562Sgshapiro interactive and delivering to an alias which resolves to 120964562Sgshapiro multiple files. 121064562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 121164562Sgshapiro greater (see below); the help function doesn't print the 121264562Sgshapiro version of sendmail any longer, instead it is placed in 121364562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 121464562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 121564562Sgshapiro skipped and a version line (#vers) is introduced. The 121664562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 121764562Sgshapiro version is found, a warning is logged. The '#vers' 121864562Sgshapiro directive should be placed at the top of the help file. 121964562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 122064562Sgshapiro disk succeeded. Suggested by Nick Christenson. 122164562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 122264562Sgshapiro length before the attempt. 122364562Sgshapiro If a forward points to a filename for delivery, change to the 122464562Sgshapiro user's uid before checking permissions on the file. This 122564562Sgshapiro allows delivery to files on NFS mounted directories where 122664562Sgshapiro root is remapped to nobody. Problem noted by Harald 122764562Sgshapiro Daeubler of Universitaet Ulm. 122864562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 122964562Sgshapiro host status files, not all files. 123064562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 123164562Sgshapiro in the queue file for the message and set when delivery 123264562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 123364562Sgshapiro Wonderworks Inc. 123464562Sgshapiro Add support for storing information between rulesets using the new 123564562Sgshapiro macro map class. This can be used to store information 123664562Sgshapiro between queue runs as well using $={persistentMacros}. 123764562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 123864562Sgshapiro of Hannover. 123964562Sgshapiro New map class arith to allow for computations in rules. The 124064562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 124164562Sgshapiro as key. The two operands are specified as arguments; the 124264562Sgshapiro lookup returns the result of the computation. For example, 124364562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 124464562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 124564562Sgshapiro Add new syntax for header declarations which decide whether to 124664562Sgshapiro include the header based on a macro rather than a mailer 124764562Sgshapiro flag: 124864562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 124964562Sgshapiro This should be used along with $={persistentMacros}. 125064562Sgshapiro It can be used for adding headers to a message based on 125164562Sgshapiro the results of check_* and header check rulesets. 125264562Sgshapiro Allow new named config file rule check_eoh which is called after 125364562Sgshapiro all of the headers have been collected. The input to the 125464562Sgshapiro ruleset the number of headers and the size of all of the 125564562Sgshapiro headers in bytes separated by $|. This ruleset along with 125664562Sgshapiro the macro storage map can be used to correlate information 125764562Sgshapiro gathered between headers and to check for missing headers. 125864562Sgshapiro See cf/README or doc/op/op.ps for an example. 125964562Sgshapiro Change the default for the MeToo option to True to correspond 126064562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 126164562Sgshapiro option is deprecated and will be removed from a future 126264562Sgshapiro version. 126364562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 126464562Sgshapiro Change the sendmail binary default for SuperSafe to True. 126564562Sgshapiro Display ruleset names in debug and address test mode output 126664562Sgshapiro if referencing a named ruleset. 126764562Sgshapiro New mailer equate m= which will limit the number of messages 126864562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 126964562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 127064562Sgshapiro using it to sort. Now all the same domains are really run 127164562Sgshapiro through the queue together. If they have the same MX host, 127264562Sgshapiro then they will have a much better opportunity to use the 127364562Sgshapiro connection cache if available. This should be a reasonable 127464562Sgshapiro performance improvement. Patch from Randall Winchester of 127564562Sgshapiro the University of Maryland. 127664562Sgshapiro If a message is rejected by a header check ruleset, log who would 127764562Sgshapiro have received the message if it had not been rejected. 127864562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 127964562Sgshapiro queue immediately. No delivery attempt is made. 128064562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 128164562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 128264562Sgshapiro COMMANDS). 128364562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 128464562Sgshapiro but for outgoing connections. 128564562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 128664562Sgshapiro error messages and logging) and Modifiers, i.e. 128764562Sgshapiro a require authentication 128864562Sgshapiro b bind to interface through which mail has 128964562Sgshapiro been received 129064562Sgshapiro c perform hostname canonification 129164562Sgshapiro f require fully qualified hostname 129264562Sgshapiro h use name of interface for outgoing HELO 129364562Sgshapiro command 129464562Sgshapiro C don't perform hostname canonification 129564562Sgshapiro E disallow ETRN (see RFC 2476) 129664562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 129764562Sgshapiro h use name of interface for HELO command 129864562Sgshapiro The version number for queue files (qf) has been incremented to 4. 129964562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 130064562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 130164562Sgshapiro Institutes of Health. 130264562Sgshapiro If a mailer dies, print the status in decimal instead of octal 130364562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 130464562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 130564562Sgshapiro Move message priority from sender to recipient logging. Suggested by 130664562Sgshapiro Ulrich Windl of the Universitat Regensburg. 130764562Sgshapiro Add support for Berkeley DB 3.X. 130864562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 130964562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 131064562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 131164562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 131264562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 131364562Sgshapiro sub-options is set on the command line. Problem noted by 131464562Sgshapiro Graeme Hewson of Oracle. 131564562Sgshapiro Randomize equal preference MX records each time delivery is 131664562Sgshapiro attempted via a new connection to a host instead of once per 131764562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 131864562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 131964562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 132064562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 132164562Sgshapiro to hosts which have dynamically assigned names. 132264562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 132364562Sgshapiro the bounce for the same reason. If the body is not 8-bit 132464562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 132564562Sgshapiro not be included in the bounce. Problem noted by Valdis 132664562Sgshapiro Kletnieks of Virginia Tech. 132764562Sgshapiro The timeout for sending a message via SMTP has been changed from 132864562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 132964562Sgshapiro simply checks for progress on sending data every 5 minutes. 133064562Sgshapiro This will detect the inability to send information quicker 133164562Sgshapiro and reduce the number of processes simply waiting to 133264562Sgshapiro timeout. 133364562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 133464562Sgshapiro interface address structure when loading the system network 133564562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 133664562Sgshapiro Nanoteq. 133764562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 133864562Sgshapiro indicates the number of interfaces to read when probing 133964562Sgshapiro for hostnames and IP addresses for class w ($=w). The 134064562Sgshapiro default value is 512. Based on idea from Reinier 134164562Sgshapiro Bezuidenhout of Nanoteq. 134264562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 134364562Sgshapiro on load average. 134464562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 134564562Sgshapiro Northern Illinois University. 134664562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 134764562Sgshapiro envelope splitting has occurred. 134864562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 134964562Sgshapiro Luke Mewburn from RMIT University. 135064562Sgshapiro Add a "/quit" command to address test mode. 135164562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 135264562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 135364562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 135464562Sgshapiro Institute. 135564562Sgshapiro The contents of a class can now be copied to another class using 135664562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 135764562Sgshapiro the items in class $={Source} into the class $={Dest}. 135864562Sgshapiro Include original envelope's error transcript in bounces created for 135964562Sgshapiro split (owner-) envelopes to see the original errors when 136064562Sgshapiro the recipients were added. Based on fix from Motonori 136164562Sgshapiro Nakamura of Kyoto University. 136264562Sgshapiro Show reason for permanent delivery errors directly after the 136364562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 136464562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 136564562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 136664562Sgshapiro If the specification for the queue run interval (-q###) has a 136764562Sgshapiro syntax error, consider the error fatal and exit. 136864562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 136964562Sgshapiro noted by Motonori Nakamura of Kyoto University. 137064562Sgshapiro On operating systems which have setlogin(2), use it to set the 137164562Sgshapiro login name to the RunAsUserName when starting as a daemon. 137264562Sgshapiro This is for delivery to programs which use getlogin(). 137364562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 137464562Sgshapiro Differentiate between "command not implemented" and "command 137564562Sgshapiro unrecognized" in the SMTP dialogue. 137664562Sgshapiro Strip returns from forward and include files.

Problem noted by Per 145464562Sgshapiro Hedeland of Ericsson. 145564562Sgshapiro mailq displays unprintable characters in addresses as their octal 145664562Sgshapiro representation and a leading backslash. This avoids problems 145764562Sgshapiro with "unprintable" characters. Problem noted by Michal 145864562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 145964562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 146064562Sgshapiro one character past the limit. This would cause subsequent 146164562Sgshapiro hops to break the line again. The '!' is now placed in 146264562Sgshapiro the last column of the limit if the line needs to be broken. 146364562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 146464562Sgshapiro from Per Hedeland of Ericsson. 146564562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 146664562Sgshapiro resolver will fall back to TCP. However, some 146764562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 146864562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 146964562Sgshapiro don't fail on ANY queries. 147064562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 147164562Sgshapiro address, do not send an empty postmaster notification DSN 147264562Sgshapiro to the postmaster.

Problem noted by Ezequiel H. Panepucci of 177464562Sgshapiro Yale University. 177564562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 177664562Sgshapiro be used for building. 177764562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 177864562Sgshapiro used for a fresh build. 177964562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 178064562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 178164562Sgshapiro ranlib. 178264562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 178364562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 178464562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 178564562Sgshapiro building of the man pages when defined. Suggested by Bryan 178664562Sgshapiro Costales. 178764562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 178864562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 178964562Sgshapiro installation of the sendmail helpfile and statistics file 179064562Sgshapiro respectively. Suggested by Bryan Costales. 179164562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 179264562Sgshapiro of Siemens Business Services. 179364562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 179464562Sgshapiro stdio library. The new buffered file I/O depends on the 179564562Sgshapiro Torek stdio library. This option can be either portable or 179664562Sgshapiro torek. 179764562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 179864562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 179964562Sgshapiro They should contain the C source files for the object files 180064562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 180164562Sgshapiro will be passed to the 'make depend' stage of compilation. 180264562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 180364562Sgshapiro in the sendmail distribution. Each has the form 180464562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 180564562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 180664562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 180764562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 180864562Sgshapiro building the distribution, but documentation on the changes 180964562Sgshapiro are in devtools/README. 181064562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 181164562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 181264562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 181364562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 181464562Sgshapiro new variable which identifies the root of the source 181564562Sgshapiro directories for all of the programs in the distribution. 181664562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 181764562Sgshapiro time. They can both still be overridden by setting the m4 181864562Sgshapiro macro. 181964562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 182064562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 182164562Sgshapiro build configurations, and places objects in obj.prefix.*/. 182264562Sgshapiro Complains as 'Build -f file' does for existing object 182364562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 182464562Sgshapiro Corporation. 182564562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 182664562Sgshapiro manual pages in the directory tree specified by 182764562Sgshapiro confMANROOTMAN. 182864562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 182964562Sgshapiro preformatted pages from the distribution. The new variable 183064562Sgshapiro confCOPY specifies the copying program. 183164562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 183264562Sgshapiro question. Suggested by Terry Lambert of Whistle 183364562Sgshapiro Communications. 183464562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 183564562Sgshapiro of the installed statistics and help files, respectively. 183664562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 183764562Sgshapiro operating system identity. Problem noted by Erik 183864562Sgshapiro Wachtenheim of Dartmouth College. 183964562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 184064562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 184164562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 184264562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 184364562Sgshapiro how to strip binaries. These are used by the new 184464562Sgshapiro install-strip target. 184564562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 184664562Sgshapiro the others (if it exists). 184764562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 184864562Sgshapiro then the default ones. 184964562Sgshapiro MAIL.LOCAL: Will not be installed setuid root. To use mail.local 185064562Sgshapiro as local delivery agent without LMTP mode, use 185164562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 185264562Sgshapiro to set the S flag. 185364562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 185464562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 185564562Sgshapiro Northern Illinois University. 185664562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 185764562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 185864562Sgshapiro the Finnish Meteorological Institute. 185964562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 186064562Sgshapiro MAILLOCK when compiling. Also requires linking with 186164562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 186264562Sgshapiro University. 186364562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 186464562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 186564562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 186664562Sgshapiro University. 186764562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 186864562Sgshapiro structure to the beginning of the program. This ensures that 186964562Sgshapiro the getservbyname() is done before any seteuid to a possibly 187064562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 187164562Sgshapiro on a Solaris system, this avoids syslog messages such as, 187264562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 187364562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 187464562Sgshapiro University. 187564562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 187664562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 187764562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 187864562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 187964562Sgshapiro characters (in LMTP mode), mail.local split the incoming 188064562Sgshapiro line up into 2046-character output lines (excluding the 188164562Sgshapiro newline). If an input line was 2047 characters long 188264562Sgshapiro (excluding CR-LF) and the last character was a '.', 188364562Sgshapiro mail.local saw it as the end of input, transfered it to the 188464562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 188564562Sgshapiro If the message was much longer, both sendmail and 188664562Sgshapiro mail.local would deadlock waiting for each other to read 188764562Sgshapiro what they have written. Problem noted by Peter Jeremy of 188864562Sgshapiro Alcatel Australia Limited. 188964562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 189064562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 189164562Sgshapiro Neil Rickert of Northern Illinois University. 189264562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 189364562Sgshapiro timeout to avoid starvation. 189464562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 189564562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 189664562Sgshapiro Infinite Monkeys & Co. 189764562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 189864562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 189964562Sgshapiro printed in a machine readable fashion and the stats file 190064562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 190164562Sgshapiro of Maryland. 190264562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 190364562Sgshapiro generated maps to the TrustedUser as specified in the 190464562Sgshapiro sendmail configuration file. 190564562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 190664562Sgshapiro configuration file to use for finding the TrustedUser 190764562Sgshapiro option. 190864562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database.

From Graeme Hewson of Oracle 191764562Sgshapiro Corporation UK. 191864562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 191964562Sgshapiro (e.g., sendmail would not drop root privileges if the 192064562Sgshapiro option was specified on the command line). Problem noted 192164562Sgshapiro by Todd C. Miller of Courtesan Consulting. 192264562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 192364562Sgshapiro Berkeley DB. Patch from Brian J.

Sites 237938032Speter which need the ability to override security can use the 238038032Speter DontBlameSendmail option. See the README file for more 238138032Speter information. 238238032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 238338032Speter if maps or alias files are in world writable directories. 238438032Speter This fixes the change added to 8.8.6 to prevent links in these 238538032Speter world writable directories. 238638032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 238738032Speter it is in a world writable directory. 238838032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 238938032Speter tty it may be able to push bytes back to the senders input. 239038032Speter Unfortunately this breaks -v mode. Problem noted by 239138032Speter Wietse Venema of the Global Security Analysis Lab at 239238032Speter IBM T.J.

Problem reported by Wolfgang Ley of DFN-CERT. 239638032Speter SECURITY: The default value for DefaultUser is now set to the uid and 239738032Speter gid of the first existing user mailnull, sendmail, or daemon 239838032Speter that has a non-zero uid. If none of these exist, sendmail 239938032Speter reverts back to the old behavior of using uid 1 and gid 1. 240038032Speter This is a security problem for Linux which has chosen that 240138032Speter uid and gid for user bin instead of daemon. If DefaultUser 240238032Speter is set in the configuration file, that value overrides this 240338032Speter default. 240438032Speter SECURITY: Since 8.8.7, the check for non-setuid binaries 240538032Speter interfered with setting an alternate group id for the 240638032Speter RunAsUser option. Problem noted by Randall Winchester of 240738032Speter the University of Maryland. 240838032Speter Add support for Berkeley DB 2.X.

Fix from John Beck of Sun 242138032Speter Microsystems. 242238032Speter On operating systems which change the process title by reusing the 242338032Speter argument vector memory, sendmail could corrupt memory if the 242438032Speter last argument was either "-q" or "-d". Problem noted by 242538032Speter Frank Langbein of the University of Stuttgart. 242638032Speter Support Local Mail Transfer Protocol (LMTP) between sendmail and 242738032Speter mail.local on the F=z flag. 242838032Speter Macro-expand the contents of the ErrMsgFile. Previously this was 242938032Speter only done if you had magic characters (0x81) to indicate 243038032Speter macro expansion. Now $x will be expanded. This means that 243138032Speter real dollar signs have to be backslash escaped. 243264562Sgshapiro TCP Wrappers expects "unknown" in the hostname argument if the 243338032Speter reverse DNS lookup for the incoming connection fails. 243438032Speter Problem noted by Randy Grimshaw of Syracuse University and 243538032Speter Wietse Venema of the Global Security Analysis Lab at 243638032Speter IBM T.J.

Fix from Andreas Luik 244338032Speter of ISA Informationssysteme GmbH. 244438032Speter Tokenize $&x expansions on right hand side of rules. This eliminates 244538032Speter the need to use tricks like $(dequote "" $&{client_name} $) 244638032Speter to cause the ${client_name} macro to be properly tokenized. 244738032Speter Add the MaxRecipientsPerMessage option: this limits the number of 244838032Speter recipients that will be accepted in a single SMTP 244938032Speter transaction. After this number is reached, sendmail 245038032Speter starts returning "452 Too many recipients" to all RCPT 245138032Speter commands. This can be used to limit the number of recipients 245238032Speter per envelope (in particular, to discourage use of the server 245338032Speter for spamming). Note: a better approach is to restrict 245438032Speter relaying entirely. 245538032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 245638032Speter to ldapx map and added timeout for ldap_open call to 245738032Speter avoid hanging sendmail in the event of hung LDAP servers. 245838032Speter Patch from Booker Bense of Stanford University. 245938032Speter Allow multiple -qI, -qR, or -qS queue run limiters. For example, 246038032Speter '-qRfoo -qRbar' would deliver mail to recipients with foo or 246138032Speter bar in their address. Patch from Allan E Johannesen of 246238032Speter Worcester Polytechnic Institute. 246338032Speter The bestmx map will now return a list of the MX servers for a host if 246438032Speter passed a column delimiter via the -z map flag. This can be 246538032Speter used to check if the server is an MX server for the recipient 246638032Speter of a message. This can be used to help prevent relaying. 246738032Speter Patch from Mitchell Blank Jr of Exec-PC. 246838032Speter Mark failures for the *file* mailer and return bounce messages to the 246938032Speter sender for those failures. 247038032Speter Prevent bogus syslog timestamps on errors in sendmail.cf by 247138032Speter preserving the TZ environment variable until TimeZoneSpec 247238032Speter has been determined.

Problem noted by Aidan Nichol 247838032Speter of Procter & Gamble. 247938032Speter The LDAP map -s flag was not properly parsed and the error message 248064562Sgshapiro given included the remainder of the arguments instead of 248138032Speter solely the argument in error. Problem noted by Aidan Nichol 248238032Speter of Procter & Gamble. 248338032Speter New DontBlameSendmail option. This option allows administrators to 248438032Speter bypass some of sendmail's file security checks at the expense 248538032Speter of system security.

A config line 253838032Speter of the form: 253938032Speter HHeader: $>Ruleset 254038032Speter causes the indicated Ruleset to be invoked on the Header 254138032Speter when read. This ruleset works like the check_* rulesets -- 254238032Speter that is, it can reject mail on the basis of the contents. 254338032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 254438032Speter from hiding their connection information in Received: 254538032Speter headers. 254638032Speter When SingleThreadDelivery is active, deliveries to locked hosts 254738032Speter are skipped. This will cause the delivering process to 254838032Speter try the next MX host or queue the message if no other MX 254938032Speter hosts are available. Suggested by Alexander Litvin. 255038032Speter The [FILE] mailer type now delivers to the file specified in the 255138032Speter A= equate of the mailer definition instead of $u. It also 255238032Speter obeys all of the F= mailer flags such as the MIME 255338032Speter 7/8 bit conversion flags. This is useful for defining 255438032Speter a mailer which delivers to the same file regardless of the 255564562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 255638032Speter Do not assume the identity of a remote connection is root@localhost 255738032Speter if the remote connection closes the socket before the 255838032Speter remote identity can be queried. 255938032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 256038032Speter Some mailers, including procmail, require that the real 256138032Speter uid is left unchanged by sendmail. Problem noted by Per 256238032Speter Hedeland of Ericsson. 256338032Speter No longer is the src/obj*/Makefile selected from a large list -- it 256438032Speter is now generated using the information in BuildTools/OS/ -- 256538032Speter some of the details are determined dynamically via 256638032Speter BuildTools/bin/configure.sh. 256738032Speter The other programs in the sendmail distribution -- mail.local, 256838032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 256938032Speter the new Build method which creates an operating system 257038032Speter specific Makefile using the information in BuildTools. 257138032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 257238032Speter a failure on one message won't affect future messages to the 257338032Speter same host). This is necessary if the remote host sends 257438032Speter a 451 error if the domain of the sender does not resolve 257538032Speter as is common in anti-spam configurations. Problem noted 257638032Speter by Mitchell Blank Jr of Exec-PC. 257738032Speter New "discard" mailer for check_* rulesets and header checking 257838032Speter rulesets. If one of the above rulesets resolves to the 257938032Speter $#discard mailer, the commands will be accepted but the 258038032Speter message will be completely discarded after it is accepting. 258138032Speter This means that even if only one of the recipients 258238032Speter resolves to the $#discard mailer, none of the recipients 258338032Speter will receive the mail. Suggested by Brian Kantor. 258438032Speter All but the last cloned envelope of a split envelope were queued 258538032Speter instead of being delivered. Problem noted by John Caruso 258638032Speter of CNET: The Computer Network. 258738032Speter Fix deadlock situation in persistent host status file locking. 258838032Speter Syslog an error if a user forward file could not be read due to 258938032Speter an error.

Suggested by Scott 260238032Speter Gifford of The Internet Ramp. 260338032Speter Sendmail would get a segmentation fault if a mailer exited with an 260438032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 260538032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 260638032Speter Institute. 260738032Speter Separate snprintf/vsnprintf routines into separate file for use by 260838032Speter mail.local. 260938032Speter Allow multiple map lookups on right hand side, e.g., 261038032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 261138032Speter Christophe Wolfhugel of the Pasteur Institute. 261238032Speter Properly generate success DSN messages if requested for aliases 261338032Speter which have owner- aliases.

Patch from Per Hedeland of 263038032Speter Ericsson. 263138032Speter Change persistent host status filename substitution so '/' is 263238032Speter replaced by ':' instead of '|' to avoid clashes. Also 263338032Speter avoid clashes with hostnames with leading dots. Fix from 263438032Speter Mitchell Blank Jr. of Exec-PC. 263538032Speter If the system lock table is full, only attempt to create a new 263638032Speter queue entry five times before giving up. Previously, it 263738032Speter was attempted indefinitely which could cause the partition 263838032Speter to run out of inodes.

The default is hash. Patch from 268938032Speter Robert Harker of Harker Systems. 269038032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 269138032Speter directory for certain programs. 269238032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 269338032Speter local mail delivery. By the default, /usr/libexec/mail.local 269438032Speter is used. This is expected to be the mail.local shipped 269538032Speter with 8.9 which is LMTP capable. The path is based on the 269638032Speter new confEBINDIR m4 variable. 269738032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 269838032Speter FEATURE(smrsh). Note that this changes the default from 269938032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 270038032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 270138032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 270238032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 270338032Speter the user to setup different .forward files for 270438032Speter user+detail addressing. 270538032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 270638032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 270738032Speter DontProbeInterfaces, and DontBlameSendmail options. 270838032Speter CONFIG: by default do not allow relaying (that is, accepting mail 270938032Speter from outside your domain and sending it to another host 271038032Speter outside your domain). 271138032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 271238032Speter any site to any site. 271338032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 271438032Speter domain as defined by the 'm' class ($=m) to relay. 271538032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 271638032Speter the MX records of the host portion of an incoming recipient. 271738032Speter CONFIG: new FEATURE(access_db) which turns on the access database 271877349Sgshapiro feature. This database gives you the ability to allow 271938032Speter or refuse to accept mail from specified domains for 272038032Speter administrative reasons. By default, names that are listed 272138032Speter as "OK" in the access db are domain names, not host names. 272238032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 272338032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 272438032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 272538032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 272638032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 272738032Speter of FEATURE(access_db) and class 'R' to lookup individual 272838032Speter host names only. 272938032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 273038032Speter using % addressing is used, e.g. user%site@othersite, 273138032Speter and othersite is in class 'R', the check_rcpt ruleset 273238032Speter will strip @othersite and recheck user@site for relaying. 273338032Speter This feature changes that behavior. It should not be 273438032Speter needed for most installations. 273538032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 273638032Speter domain portion of the mail sender is a local host. This 273738032Speter should only be used if absolutely necessary as it opens 273838032Speter a window for spammers. Patch from Randall S. Winchester of 273938032Speter the University of Maryland. 274038032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 274138032Speter block incoming mail destined for certain recipient 274238032Speter usernames, hostnames, or addresses. 274338032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 274438032Speter refused if the host part of the argument to MAIL FROM: cannot 274538032Speter be located in the host name service (e.g., DNS). 274638032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 274738032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 274838032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 274938032Speter MAIL FROM: senders which do not include a domain. 275038032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 275138032Speter Realtime Blackhole List. You can specify the RBL name 275238032Speter server to contact by specifying it as an optional argument. 275338032Speter The default is rbl.maps.vix.com. For details, see 275438032Speter http://maps.vix.com/rbl/. 275538032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 275638032Speter Local_check_rcpt from check_relay, check_mail, and 275738032Speter check_rcpt. Users with local rulesets should place the 275838032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 275938032Speter returns $#OK, the message is accepted. If the ruleset 276038032Speter returns a mailer, the appropriate action is taken, else 276138032Speter the return of the ruleset is ignored. 276238032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 276338032Speter default to support file, :include:, and program deliveries. 276438032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 276538032Speter pick the proper default value. See the SECURITY note 276638032Speter above for more information. 276738032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 276838032Speter no-op. Patch from Kari Hurtta of the Finnish 276938032Speter Meteorological Institute. 277038032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 277138032Speter daemon since DEC's /bin/mail will drop the envelope 277238032Speter sender if run as mailnull. See the Digital UNIX section 277338032Speter of src/README for more information. Problem noted by 277438032Speter Kari Hurtta of the Finnish Meteorological Institute. 277538032Speter CONFIG: .cf files are now stored in the same directory with the 277638032Speter .mc files instead of in the obj directory. 277764562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 277838032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 277938032Speter setting SingleLineFromHeader, AllowBogusHELO, and 278038032Speter MustQuoteChars respectively. 278138032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout.

Problem noted by Kari Hurtta of the Finnish 289938032Speter Meteorological Institute. 290038032Speter If /usr/tmp/dead.letter already existed, sendmail could not 290138032Speter add additional bounces to it. Problem noted by Thomas J. 290238032Speter Arseneault of SRI International. 290338032Speter If an SMTP mailer used a non-standard port number for the outgoing 290438032Speter connection, it would be displayed incorrectly in verbose mode. 290538032Speter Problem noted by John Kennedy of Cal State University, Chico. 290638032Speter Log the ETRN parameter specified by the client before altering them 290738032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 290838032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 290938032Speter User unknown with bogus delay= values. Change them to log 291038032Speter the same as compliant addresses. Problem noted by Kari E. 291138032Speter Hurtta of the Finnish Meteorological Institute. 291238032Speter Ignore the debug resolver option unless using sendmail debug trace 291338032Speter option for resolver. Problem noted by Greg Nichols of Wind 291438032Speter River Systems. 291538032Speter If SingleThreadDelivery was enabled and the remote server returned a 291638032Speter protocol error on the DATA command, the connection would be 291738032Speter closed but the persistent host status file would not be 291838032Speter unlocked so other sendmail processes could not deliver to 291938032Speter that host. Problem noted by Peter Wemm of DIALix. 292038032Speter If queueing up a message due to an expensive mailer, don't increment 292138032Speter the number of delivery attempts or set the last delivery 292238032Speter attempt time so the message will be delivered on the next 292338032Speter queue run regardless of MinQueueAge. Problem noted by 292438032Speter Brian J. Coan of the Institute for Global Communications. 292538032Speter Authentication warnings of "Processed from queue _directory_" and 292638032Speter "Processed by _username_ with -C _filename_" would be logged 292738032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 292838032Speter of the Finnish Meteorological Institute. 292938032Speter Use a better heuristic for detecting GDBM. 293038032Speter Log null connections on dropped connections. Problem noted by 293138032Speter Jon Lewis of Florida Digital Turnpike. 293238032Speter If class dbm maps are rebuilt, sendmail will now detect this and 293338032Speter reopen the map. Previously, they could give stale 293438032Speter results during a single message processing (but would 293538032Speter recover when the next message was received). Fix from 293638032Speter Joe Pruett of Q7 Enterprises. 293738032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 293838032Speter requests. Problem noted by Kari E. Hurtta of the 293938032Speter Finnish Meteorological Institute. 294038032Speter Do not send a bounce message back to the sender regarding bad 294138032Speter recipients if the SMTP connection is dropped before the 294238032Speter message is accepted. Problem noted by Kari E. Hurtta of the 294338032Speter Finnish Meteorological Institute. 294438032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 294538032Speter sendmail via a UNIX pipe. This will allow rulesets using 294638032Speter $&{client_name} to process without sending the string through 294738032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 294838032Speter A combination of deferred delivery mode, a double bounce situation, 294938032Speter and the inability to save a bounce message to 295038032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 295138032Speter to postmaster but not remove the offending envelope from the 295238032Speter queue causing it to create a new bounce message each time the 295338032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 295438032Speter Associates. 295538032Speter Remove newlines from hostname information returned via DNS. There are 295638032Speter no known security implications of newlines in hostnames as 295738032Speter sendmail filters newlines in all vital areas; however, this 295838032Speter could cause confusing error messages. 295938032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 296038032Speter rejected if any of the specified addresses were bad. This 296138032Speter behavior was modified to only reject the bad addresses and not 296238032Speter the entire message. Problem noted by Jozsef Hollosi of 296338032Speter SuperNet, Inc. 296438032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 296538032Speter Bryan Costales of InfoBeat, Inc. 296638032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 296738032Speter mailers. Problem noted by Kari E. Hurtta of the 296838032Speter Finnish Meteorological Institute. 296938032Speter An error in calculating the available space in the list of addresses 297038032Speter for logging deliveries could cause an address to be silently 297138032Speter dropped. 297238032Speter Include the initial user environment if sendmail is restarted via 297338032Speter a HUP signal. This will give room for the process title. 297438032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 297538032Speter Mail could be delivered without a body if the machine does not 297638032Speter support flock locking and runs out of processes during 297738032Speter delivery. Fix from Chuck Lever of the University of Michigan. 297838032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 297938032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 298038032Speter Institute. 298138032Speter Make sure non-rebuildable database maps are opened before the 298264562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 298338032Speter are needed for verifying the left hand side of the aliases. 298438032Speter Problem noted by Lloyd Parkes of Victoria University. 298538032Speter Make sure sender RFC822 source route addresses are alias expanded for 298638032Speter bounce messages. Problem noted by Juergen Georgi of 298738032Speter RUS University of Stuttgart. 298838032Speter Minor lint fixes. 298938032Speter Return a temporary error instead of a permanent error if an LDAP map 299038032Speter search returns an error. This will allow sequenced maps which 299138032Speter use other LDAP servers to be checked. Fix from Booker Bense 299238032Speter of Stanford University. 299338032Speter When automatically converting from quoted printable to 8bit text do 299438032Speter not pad bare linefeeds with a space. Problem noted by Theo 299538032Speter Nolte of the University of Technology Aachen, Germany. 299638032Speter Portability: 299738032Speter Non-standard C compilers may have had a problem compiling 299838032Speter conf.c due to a standard C external declaration of 299938032Speter setproctitle(). Problem noted by Ted Roberts of 300038032Speter Electronic Data Systems. 300138032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 300238032Speter Jagielski of jaguNET Access Services. 300338032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 300438032Speter Digital UNIX: Digital UNIX (and possibly others) moves 300538032Speter loader environment variables into the loader memory 300638032Speter area. If one of these environment variables (such as 300738032Speter LD_LIBRARY_PATH) was the last environment variable, 300838032Speter an invalid memory address would be used by the process 300938032Speter title routine causing memory corruption. Problem 301038032Speter noted by Sam Hartman of Mesa Internet Systems. 301138032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 301238032Speter chownsafe() to always return 0 even if the OS does 301338032Speter not permit file giveaways. Problem noted by 301438032Speter Yasutaka Sumi of The University of Tokyo. 301564562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 301638032Speter Gerald Rinske of Siemens Business Services VAS. 301738032Speter Linux: Pad process title with NULLs. Problem noted by 301838032Speter Jon Lewis of Florida Digital Turnpike. 301938032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 302038032Speter incorrect value for the number of interfaces. 302138032Speter Problem noted by Chris Loelke of JetStream Internet 302238032Speter Services. 302338032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 302438032Speter Rinske of Siemens Business Services VAS. 302538032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 302638032Speter used on a Solaris machine. Problem noted by 302738032Speter Stephen Ma of Jtec Pty Limited. 302838032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 302938032Speter Services VAS. 303038032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 303138032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 303238032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 303338032Speter Ericsson. 303438032Speter 303564562Sgshapiro8.8.7/8.8.7 1997/08/03 303638032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 303738032Speter an exclusive lock already set -- i.e., almost all systems 303838032Speter except 4.4-BSD derived systems), the initial attempt at 303938032Speter rebuilding aliases file if the database didn't already 304038032Speter exist would fail. Patch from Raymund Will of LST Software 304138032Speter GmbH. 304238032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 304338032Speter Problem noted by Fredrik J�nsson of the Royal Institute 304438032Speter of Technology, Stockholm. 304538032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 304638032Speter some environments could give "multiple definitions" for these 304738032Speter routines during compilation. If using TCP Wrappers, assume 304838032Speter that these routines are included as though they were in the 304938032Speter C library. Patch from Robert La Ferla. 305038032Speter When a NEWDB database map was rebuilt at the same time it was being 305138032Speter used by a queue run, the maps could be left locked for the 305238032Speter duration of the queue run, causing other processes to hang. 305338032Speter Problem noted by Kendall Libby of Shore.NET. 305438032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 305538032Speter mail was passed on without any recipient header. This could 305638032Speter cause problems downstream. Problem noted by Xander Jansen 305738032Speter of SURFnet ExpertiseCentrum. 305838032Speter Give error when GDBM is used with sendmail. GDBM's locking and 305938032Speter linking of the .dir and .pag files interferes with sendmail's 306038032Speter locking and security checks. Problems noted by Fyodor 306138032Speter Yarochkin of the Kyrgyz Republic FreeNet. 306238032Speter Don't fsync qf files if SuperSafe option is not set. 306338032Speter Avoid extra calls to gethostbyname for addresses for which a 306438032Speter gethostbyaddr found no value. Also, ignore any returns 306538032Speter from gethostbyaddr that look like a dotted quad. 306638032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 306738032Speter "may be forged", since at the network level we pretty much 306838032Speter have to assume that the information is good. 306938032Speter In some cases, errors during an SMTP session could leave files 307038032Speter open or locked. 307138032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 307238032Speter Better handling of non-setuid binaries -- avoids certain obnoxious 307338032Speter errors during testing. 307438032Speter Errors in file locking of NEWDB maps had the incorrect file name 307538032Speter printed in the error message. 307638032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 307738032Speter missing parameter were issued, the EHLO behaved like a HELO. 307838032Speter Load limiting never kicked in for incoming SMTP transactions if the 307943730Speter DeliveryMode=background and any recipient was an alias or 308038032Speter had a .forward file. From Nik Conwell of Boston University. 308138032Speter On some non-Posix systems, the decision of whether chown(2) permits 308238032Speter file giveaway was undefined. From Tetsu Ushijima of the 308338032Speter Tokyo Institute of Technology. 308438032Speter Fix race condition that could cause the body of a message to be 308538032Speter lost (so only the header was delivered). This only occurs 308638032Speter on systems that do not use flock(2), and only when a queue 308738032Speter runner runs during a critical section in another message 308838032Speter delivery. Based on a patch from Steve Schweinhart of 308938032Speter Results Computing. 309038032Speter If a qf file was found in a mail queue directory that had a problem 309138032Speter (wrong ownership, bad format, etc.) and the file name was 309238032Speter exactly MAXQFNAME bytes long, then instead of being tried 309338032Speter once, it would be tried on every queue run. Problem noted 309438032Speter by Bryan Costales of Mercury Mail. 309538032Speter If the system supports an st_gen field in the status structure, 309638032Speter include it when reporting that a file has changed after open. 309738032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 309838032Speter This out to be checked as well as reported, since it is 309938032Speter theoretically possible for an attacker to remove a file after 310038032Speter it is opened and replace it with another file that has the 310138032Speter same i-number, but some filesystems (notably AFS) return 310238032Speter garbage in this field, and hence always look like the file 310338032Speter has changed. As a practical matter this is not a security 310438032Speter problem, since the files can be neither hard nor soft links, 310538032Speter and on no filesystem (that I am aware of) is it possible to 310638032Speter have two files on the same filesystem with the same i-number 310738032Speter simultaneously. 310838032Speter Delete the root Makefile from the distribution -- it is only for 310938032Speter use internally, and does not work at customer sites. 311038032Speter Fix botch that caused the second MAIL FROM: command in a single 311138032Speter transaction to clear the entire transaction. Problem 311238032Speter noted by John Kennedy of Cal State University, Chico. 311338032Speter Work properly on machines that have _PATH_VARTMP defined without 311438032Speter a trailing slash. (And a pox on vendors that decide to 311538032Speter ignore the established conventions!) Problem noted by 311638032Speter Gregory Neil Shapiro of WPI. 311738032Speter Internal changes to make it easier to add another protocol family 311838032Speter (intended for IPv6). Patches are from John Kennedy of 311938032Speter CSU Chico. 312038032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 312138032Speter an extra space at the beginning of some lines. Problem 312238032Speter noted by Charles Karney of Princeton University; fix based 312338032Speter on a patch from Christophe Wolfhugel. 312438032Speter Portability: 312538032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 312638032Speter with the _Sendmail_ book, 2nd edition. Note that 312738032Speter the book is actually wrong: _PATH_SENDMAILCF should 312838032Speter be used instead. 312938032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 313038032Speter of Argonne National Laboratory. 313138032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 313238032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 313338032Speter SunOS: Include <memory.h> to fix warning from util.c. From 313438032Speter James Aldridge of EUnet Ltd. 313538032Speter Solaris: Change STDIR (location of status file) to /etc/mail 313638032Speter in Makefiles. 313738032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 313838032Speter Makefiles. Use NEWDB on Linux instead. 313938032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 314038032Speter exists but behaves differently than other OSes. 314138032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 314238032Speter around the problem. Problem noted by Tom Moore of 314338032Speter NCR Corp. 314438032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 314538032Speter noted by Tom Smith of Digital Equipment Corp. 314638032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 314738032Speter noted by Tom Good of the Community Access Information 314838032Speter Resource Network 314938032Speter SCO 4.2: compile problems caused by a change in the type of 315038032Speter the "length" parameters passed to accept, getpeername, 315138032Speter getsockname, and getsockopt. Adds new compile flags 315238032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.

This makes it possible to create a root 319738032Speter owned file in an arbitrary directory by inserting the symlink 319838032Speter into a writable directory after the initial lstat(2) check 319938032Speter determined that the file did not exist. The only verified 320038032Speter example of a system having these odd semantics for O_EXCL 320138032Speter and symbolic links was HP-UX prior to version 9.07. Most 320238032Speter systems do not have the problem, since a exclusive create 320338032Speter of a file disallows symbolic links. Systems that have been 320438032Speter verified to NOT have the problem include AIX 3.x, *BSD, 320538032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 320638032Speter and Ultrix. This is a potential exposure on systems that 320738032Speter have this bug and which do not have a MAILER-DAEMON alias 320838032Speter pointing at a legitimate account, since this will cause old 320938032Speter mail to be dropped in /var/tmp/dead.letter. 321038032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 321138032Speter if maps or alias files are in world writable directories. 321238032Speter If your system has alias maps in writable directories, it 321338032Speter is potentially possible for an attacker to replace the .db 321438032Speter (or .dir and .pag) files by symbolic links pointing at 321538032Speter another database; this can be used either to expose 321638032Speter information (e.g., by pointing an alias file at /etc/spwd.db 321738032Speter and probing for accounts), or as a denial-of-service attack 321838032Speter (by trashing the password database). The fix disallows 321938032Speter symbolic links entirely when rebuilding alias files or on 322038032Speter maps that are in writable directories, and always warns on 322138032Speter writable directories; 8.9 will probably consider writable 322238032Speter directories to be fatal errors. This does not represent an 322338032Speter exposure on systems that have alias files in unwritable 322438032Speter system directories. 322538032Speter SECURITY: disallow .forward or :include: files that are links (hard 322638032Speter or soft) if the parent directory (or any directory in the 322738032Speter path) is writable by anyone other than the owner. This is 322838032Speter similar to the previous case for user files. This change 322938032Speter should not affect most systems, but is necessary to prevent 323038032Speter an attacker who can write the directory from pointing such 323138032Speter files at other files that are readable only by the owner. 323238032Speter SECURITY: Tighten safechown rules: many systems will say that they 323338032Speter have a safe (restricted to root) chown even on files that 323438032Speter are mounted from another system that allows owners to give 323538032Speter away files. The new rules are very strict, trusting file 323638032Speter ownership only in those few cases where the system has 323738032Speter been verified to be at least as paranoid as necessary. 323838032Speter However, it is possible to relax the rules to partially 323938032Speter trust the ownership if the directory path is not world or 324038032Speter group writable. This might allow someone who has a legitimate 324138032Speter :include: file (referenced directly from /etc/aliases) to 324238032Speter become another non-root user if the :include: file is in a 324338032Speter non-writable directory on an NFS-mounted filesystem where 324438032Speter the local system says that giveaway is denied but it is 324538032Speter actually permitted. I believe this to be a very small set 324638032Speter of cases. If in doubt, do not point :include: aliases at 324738032Speter NFS-mounted filesystems. 324838032Speter SECURITY: When setting a numeric group id using the RunAsUser option 324938032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 325038032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 325138032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 325238032Speter The user id was still set properly. Problem noted by Uli 325338032Speter Pralle of the Technical University of Berlin. 325438032Speter Save the initial gid set for use when checking for if the 325538032Speter PrivacyOptions=restrictmailq option is set. Problem reported 325638032Speter by Wolfgang Ley of DFN-CERT. 325738032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 325838032Speter failure on one message won't affect future messages to the 325938032Speter same host). 326038032Speter IP source route printing had an "off by one" error that would 326138032Speter affect any options that came after the route option. Patch 326238032Speter from Theo de Raadt. 326338032Speter The "Message is too large" error didn't successfully bounce the error 326438032Speter back to the sender. Problem reported by Stephen More of 326538032Speter PSI; patch from Gregory Neil Shapiro of WPI. 326638032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 326738032Speter of 5.1.3); it apparently gets used in multiple ways. 326838032Speter Suggested by John Myers of Portola Communications. 326938032Speter Fix possible extra null byte generated during collection if errors 327038032Speter occur at the beginning of the stream. Patch contributed by 327138032Speter Andrey A. Chernov and Gregory Neil Shapiro. 327238032Speter Code changes to avoid possible reentrant call of malloc/free within 327338032Speter a signal handler. Problem noted by John Beck of Sun 327438032Speter Microsystems. 327538032Speter Move map initialization to be earlier so that check_relay ruleset 327638032Speter will have the latest version of the map data. Problem noted 327738032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 327838032Speter If there are fatal errors during the collection phase (e.g., message 327938032Speter too large) don't send the bogus message. 328038032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 328138032Speter have errors and have owner- aliases. Problem noted by Michael 328238032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 328338032Speter Avoid null pointer dereference on illegal Boundary= parameters in 328438032Speter multipart/mixed Content-Type: header. Problem noted by 328538032Speter Richard Muirden of RMIT University. 328638032Speter Always print error messages during newaliases (-bi) even if the 328738032Speter ErrorMode is not set to "print". Fix from Gregory Neil 328838032Speter Shapiro. 328938032Speter Test mode could core dump if you did a /map lookup in an optional map 329038032Speter that could not be opened. Based on a fix from John Beck of 329138032Speter Sun Microsystems. 329238032Speter If DNS is misconfigured so that the last MX record tried points to 329338032Speter a host that does not have an A record, but other MX records 329438032Speter pointed to something reasonable, don't bounce the message 329538032Speter with a "host unknown" error. Note that this should really 329638032Speter be fixed in the zone file for the domain. Problem noted by 329738032Speter Joe Rhett of Navigist, Inc. 329838032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 329938032Speter the message as having been tried; otherwise the next queue 330038032Speter run will not realize that this is a second attempt and will 330138032Speter retry immediately. Problem noted by Bryan Costales of 330238032Speter Mercury Mail. 330338032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 330438032Speter will be run until the later setting of the clock is reached. 330538032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 330638032Speter Morgan Stanley. 330738032Speter If the load average rises above the cutoff threshold (above which 330838032Speter sendmail will not process the queue at all) during a queue 330938032Speter run, abort the queue run immediately. Problem noted by 331038032Speter Bryan Costales of Mercury Mail. 331138032Speter The variable queue processing algorithm (based on the message size, 331238032Speter number of recipients, message precedence, and job age) was 331338032Speter non-functional -- either the entire queue was processed or 331438032Speter none of the queue was processed. The updated algorithm 331538032Speter does no queue run if a single recipient zero size job will 331638032Speter not be run. 331738032Speter If there is a fatal ("panic") message that will cause sendmail to 331838032Speter die immediately, never hold the error message for future 331938032Speter printing. 332038032Speter Force ErrorMode=print in -bt mode so that all errors are printed 332138032Speter regardless of the setting of the ErrorMode option in the 332238032Speter configuration file. Patch from Gregory Neil Shapiro. 332338032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 332438032Speter routine available in one of the libraries. Use it in conf.h. 332538032Speter The -m (match only) flag now works on host class maps. 332638032Speter If class hash or btree maps are rebuilt, sendmail will now detect 332738032Speter this and reopen the map. Previously, they could give 332838032Speter erroneous results during a single message processing 332938032Speter (but would recover when the next message was received). 333038032Speter Don't delete zero length queue files when doing queue runs until the 333138032Speter files are at least ten minutes old. This avoids a potential 333238032Speter race condition: the creator creates the qf file, getting back 333338032Speter a file descriptor. The queue runner locks it and deletes it 333438032Speter because it is zero length. The creator then writes the 333538032Speter descriptor that is now for a disconnected file, and the 333638032Speter job goes away. Based on a suggestion by Bryan Costales. 333738032Speter When determining the "validated" host name ($_ macro), do a forward 333838032Speter (A) DNS lookup on the result of the PTR lookup and compare 333938032Speter results. If they differ or if the PTR lookup fails, tag the 334038032Speter address as "may be forged". 334138032Speter Log null connections (i.e., hosts that connect but do not do any 334238032Speter substantive activity on the connection before disconnecting; 334338032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 334438032Speter Always permit "writes" to /dev/null regardless of the link count. 334538032Speter This is safe because /dev/null is special cased, and no open 334638032Speter or write is ever actually attempted. Patch from Villy Kruse 334738032Speter of TwinCom. 334838032Speter If a message cannot be sent because of a 552 (exceeded storage 334938032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 335038032Speter was given, don't return the body in the bounce, since there 335138032Speter is a very good chance that the message will double-bounce. 335238032Speter Fix possible line truncation if a quoted-printable had an =00 escape 335338032Speter in the body. Problem noted by Charles Karney of the Princeton 335438032Speter Plasma Physics Laboratory. 335538032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 335638032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 335738032Speter Institute. 335838032Speter The MaxDaemonChildren option wasn't applying to queue runs as 335938032Speter documented. Note that this increases the potential denial 336038032Speter of service problems with this option: an attacker can 336138032Speter connect many times, and thereby lock out queue runs as well 336238032Speter as incoming connections. If you use this option, you should 336338032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 336438032Speter to avoid this attack. Failure to limit noted by Matthew 336538032Speter Dillon of BEST Internet Communications. 336638032Speter Always give a message in newaliases if alias files cannot be 336738032Speter opened instead of failing silently. Suggested by Gregory 336838032Speter Neil Shapiro. This change makes the code match the O'Reilly 336938032Speter book (2nd edition). 337038032Speter Some older versions of the resolver could return with h_errno == -1 337138032Speter if no name server could be reached, causing mail to bounce 337238032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 337338032Speter John Beck of SunSoft. 337438032Speter If a :include: file is owned by a user that does not have an entry 337538032Speter in the passwd file, sendmail could dereference a null pointer. 337638032Speter Problem noted by Satish Mynam of Sun Microsystems. 337738032Speter Take precautions to make sure that the SMTP protocol cannot get out 337838032Speter of sync if (for example) an alias file cannot be opened. 337938032Speter Fix a possible race condition that can cause a SIGALRM to come in 338038032Speter immediately after a SIGHUP, causing the new sendmail to die. 338138032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 338238032Speter from Villy Kruse of TwinCom. 338338032Speter Ignore improperly formatted SMTP reply codes. Previously these were 338438032Speter partially processed, which could cause confusing error 338538032Speter returns. 338638032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 338738032Speter on some architectures. 338838032Speter Portability: 338938032Speter A/UX: from Jim Jagielski of NASA/GSFC. 339038032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 339138032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 339238032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 339338032Speter defined. Problem reported by A Sun of the University 339438032Speter of Washington. 339538032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 339638032Speter the system rather than guessing at compile time. 339738032Speter Patch contributed by John Beck of Sun Microsystems. 339838032Speter Intel Paragon: from Wendy Lin of Purdue University. 339938032Speter GNU Hurd: from Miles Bader of the GNU project. 340038032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 340138032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 340238032Speter Unfortunately releasing them opens a race condition, 340338032Speter but there appears to be no fix for this. Patch from 340438032Speter Gregory Neil Shapiro. 340538032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 340638032Speter Solaris: a bug in strcasecmp caused characters with the 340738032Speter high order bit set to apparently randomly match 340838032Speter letters -- for example, $| (0233) matches "i" and "I". 340938032Speter Problem noted by John Gregson of the University of 341038032Speter Cambridge. 341138032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 341238032Speter Kari Hurtta. 341338032Speter IRIX 6.x: Create Makefiles for systems that claim to be 341438032Speter IRIX64 but are 6.2 or higher (so use the regular 341538032Speter IRIX Makefile). 341638032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 341738032Speter Problem noted by Eric Hagberg of Morgan Stanley. 341838032Speter CONFIG: Some canonification was still done for UUCP-like addresses 341938032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 342038032Speter Brian Candler. 342138032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 342238032Speter local names as local. Problem noted by Jeff Polk of BSDI; 342338032Speter fix provided by Gregory Neil Shapiro. 342438032Speter CONFIG: The "local:user" syntax entries in mailertables and other 342538032Speter "mailer:user" syntax locations returned an incorrect value 342638032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 342738032Speter CONFIG: Retain "+detail" information when forwarding mail to a 342838032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 342938032Speter Guenther of Gustavus Adolphus College. 343038032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 343138032Speter rules are the same as for aliasing. Based on a patch from 343238032Speter Gregory Neil Shapiro. 343338032Speter CONFIG: Break up parsing rules into several pieces; this should 343438032Speter have no functional change in this release, but makes it 343538032Speter possible to have better anti-spam rulesets in the future. 343638032Speter CONFIG: Disallow double dots in host names to avoid having the 343738032Speter HostStatusDirectory store status under the wrong name. 343838032Speter In some cases this can be used as a denial-of-service attack. 343938032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 344038032Speter Gregory Neil Shapiro. 344138032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 344238032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 344338032Speter don't include From_, and convert to 8-bit). Suggestions 344438032Speter from Kimmo Suominen and Roderick Schertler. 344564562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 344638032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 344738032Speter was specified, even when it wasn't. 344838032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 344938032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 345038032Speter "slip in" a symbolic link between the lstat(2) call and the 345138032Speter exclusive open. This is only a problem on System V derived 345238032Speter systems that allow an exclusive create on files that are 345338032Speter symbolic links pointing nowhere. 345438032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 345538032Speter not reset back to root, which on some systems would cause 345638032Speter later mailboxes to fail. Also, any partial message would 345738032Speter not be truncated, which could result in repeated deliveries. 345838032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 345938032Speter developers). 346038032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 346138032Speter change to the sendmail map code was made in 8.8.3. Problem 346238032Speter noted by Gregory Neil Shapiro. 346338032Speter MAKEMAP: Give warnings on file problems such as map files that are 346438032Speter symbolic links; although makemap is not setuid root, it is 346538032Speter often run as root and hence has the potential for the same 346638032Speter sorts of problems as alias rebuilds. 346738032Speter MAKEMAP: Change compilation so that it will link properly on 346838032Speter NEXTSTEP. 346938032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 347038032Speter Accept an optional list of arguments following the server 347138032Speter name for the ETRN arguments to use (instead of $=w).

This 347538032Speter Perl script converts GECOS information in the /etc/passwd 347638032Speter file into aliases, allowing for faster access to full name 347738032Speter lookups; it is also clever about adding aliases (to root) 347838032Speter for system accounts. 347938032Speter NEW FILES: 348038032Speter src/safefile.c 348138032Speter cf/ostype/gnuhurd.m4 348238032Speter cf/ostype/irix6.m4 348338032Speter contrib/passwd-to-alias.pl 348438032Speter src/Makefiles/Makefile.IRIX64.6.1 348538032Speter src/Makefiles/Makefile.IRIX64.6.x 348638032Speter RENAMED FILES: 348738032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 348838032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 348938032Speter 349064562Sgshapiro8.8.5/8.8.5 1997/01/21 349138032Speter SECURITY: Clear out group list during startup. Without this, sendmail 349238032Speter will continue to run with the group permissions of the caller, 349338032Speter even if RunAsUser is specified. 349438032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 349538032Speter to any known attack, but it's best to be conservative. 349638032Speter Suggested by Peter Wemm of DIALix. 349738032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 349838032Speter security implications. Patch from Alex Garthwaite of the 349938032Speter University of Pennsylvania. 350038032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 350138032Speter would truncate the address after "Full". Although the -f 350238032Speter syntax is incorrect (since it is in the envelope, it 350338032Speter shouldn't have comments and full names), the failure mode 350438032Speter was unnecessarily awful. 350538032Speter Fix a possible null pointer dereference when converting 8-bit data 350638032Speter to a 7-bit format. Problem noted by Jim Hutchins of 350738032Speter Sandia National Labs and David James of British Telecom. 350838032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 350938032Speter runs. Although this really shouldn't be used (F=9 is for 351038032Speter final delivery only, and using it on an SMTP mailer makes 351138032Speter it possible for a message to be converted from 8->7->8->7 351238032Speter bits several times), it shouldn't have failed with a syserr. 351338032Speter Problem noted by Eric Hagberg of Morgan Stanley. 351438032Speter _Really_ fix the multiple :maildrop code in the user database 351538032Speter module. Patch from Roy Mongiovi of Georgia Tech. 351638032Speter Let F lines in the configuration file actually read root-only 351738032Speter files if the configuration file is safe. Based on a 351838032Speter patch from Keith Reynolds of SCO. 351938032Speter ETRN followed by QUIT would hold the connection open until the queue 352038032Speter run completed. Problem noted by Truck Lewis of TDK 352138032Speter Semiconductor Corp. 352238032Speter It turns out that despite the documentation, the TCP wrappers library 352338032Speter does _not_ log rejected connections. Do the logging ourselves. 352438032Speter Problem noted by Fletcher Mattox of the University of Texas 352538032Speter at Austin. 352638032Speter If sendmail finds a qf file in its queue directory that is an unknown 352738032Speter version (e.g., when backing out to an old version), the 352838032Speter error is reported on every queue run. Change it to only 352938032Speter give the error once (and rename the qf => Qf). Patch from 353038032Speter William A. Gianopoulos of Raytheon Company. 353138032Speter Start a new session when doing background delivery; currently it 353238032Speter ignored signals but didn't start a new signal, that caused 353338032Speter some problems if a background process tried to send mail 353438032Speter under certain circumstances. Problem noted by Eric Hagberg 353538032Speter of Morgan Stanley; fix from Kari Hurtta. 353638032Speter Simplify test for skipping a queue run to just check if the current 353738032Speter load average is >= the queueing load average. Previously 353838032Speter the check factored in some other parameters that caused it 353938032Speter to essentially never skip the queue run. Patch from Bryan 354038032Speter Costales. 354138032Speter If the SMTP server is running in "nullserver" mode (that is, it is 354238032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 354338032Speter (25) commands; this helps prevent a bad guy from putting 354438032Speter you into a tight loop as a denial-of-service attack. Based 354538032Speter on an e-mail conversation with Brad Knowles of AOL. 354638032Speter Slow down when too many "light weight" commands have been issued; 354738032Speter this helps prevent a class of denial-of-service attacks. 354838032Speter The current values and defaults are: 354938032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 355038032Speter MAXHELOCOMMANDS 3 HELO, EHLO 355138032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 355238032Speter MAXETRNCOMMANDS 8 ETRN 355338032Speter These will probably be configurable in a future release. 355438032Speter On systems that have uid_t typedefed to be an unsigned short, programs 355538032Speter that had the F=S flag and no U= equate would be invoked with 355638032Speter the real uid set to 65535 rather than being left unchanged. 355738032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 355838032Speter by Steve Hubert of the University of Washington, Seattle. 355938032Speter Mail that was Quoted-Printable encoded and had a soft line break on 356038032Speter the last line (i.e., an incomplete continuation) had the last 356138032Speter line dropped. Since this appears to be illegal it isn't 356238032Speter clear what to do with it, but flushing the last line seems 356338032Speter to be a better "fail soft" approach. Based on a patch from 356438032Speter Eric Hagberg. 356538032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 356638032Speter bogus HELO command still causes the "Polite people say HELO 356738032Speter first" error message. Problem pointed out by Chris Thomas 356838032Speter of UCLA; patch from John Beck of SunSoft. 356938032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 357071345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 357171345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 357271345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 357338032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 357438032Speter in a DATA transaction to be sticky; these can occur because 357538032Speter a message is too large, and smaller messages should still go 357638032Speter through. Problem noted by Matt Dillon of Best Internet 357738032Speter Communications. 357838032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 357938032Speter had been successfully delivered to the envelope sender. 358038032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 358138032Speter Gregory Neil Shapiro of WPI. 358238032Speter Give better diagnostics on long alias lines. Based on code contributed 358338032Speter by Patrick Gosling of the University of Cambridge. 358438032Speter Increase the number of virtual interfaces that will be probed for 358538032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 358638032Speter PORTABILITY: 358738032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 358838032Speter Toshiaki Nomura of Fujitsu Limited. 358938032Speter SunOS with LDAP support: compile problems with struct timeval. 359038032Speter Patch from Nick Cuccia of TCSI Corporation. 359138032Speter SCO: from Keith Reynolds of SCO. 359238032Speter Solaris: kstat load average computation wasn't being used. 359338032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 359438032Speter (Moscow). 359538032Speter OpenBSD: from Jason Downs of teeny.org. 359638032Speter Altos System V: from Tim Rice. 359738032Speter Solaris 2.5: from Alan Perry of SunSoft. 359838032Speter Solaris 2.6: from John Beck of SunSoft. 359938032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 360038032Speter of Pratt & Whitney <miorelli@pweh.com>. 360138032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 360238032Speter _just_right_ yet. Tweak it again. I'll omit the names 360338032Speter of the "contributors" (quantity two) in this one case. 360438032Speter As of now, NO MORE DISCUSSION about the syntax of the 360538032Speter Received: line. 360638032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 360738032Speter it never inserts that class into the output file. Fix it 360838032Speter so it will honor EXPOSED_USER but will _not_ include root 360938032Speter automatically in this class. Problem noted by Ronan KERYELL 361038032Speter of Centre de Recherche en Informatique de l'�cole Nationale 361138032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 361238032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 361338032Speter such as LUSER_RELAY. This change permits the following 361438032Speter syntaxes: ``local:'' will send to the same user on the 361538032Speter local machine (e.g., in a mailertable entry for "host", 361638032Speter ``local:'' will cause an address addressed to user@host to 361738032Speter go to user on the local machone). ``local:user'' will send 361838032Speter to the named user on the local machine. ``local:user@host'' 361938032Speter is equivalent to ``local:user'' (the host is ignored). In 362038032Speter all cases, the original user@host is passed in $@ (i.e., the 362138032Speter detail information). Inspired by a report from Michael Fuhr. 362238032Speter CONFIG: Strip quotes from the first word of an "error:" host 362338032Speter indication. This lets you set (for example) the LUSER_RELAY 362438032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 362538032Speter of the \" so that the resulting string is properly quoted. 362638032Speter Problem noted by Gregory Neil Shapiro of WPI. 362738032Speter OP.ME: documentation was inconsistent about whether sendmail did a 362838032Speter NOOP or a RSET to probe the connection (it does a RSET). 362938032Speter Inconsistency noted by Deeran Peethamparam. 363038032Speter OP.ME: insert additional blank pages so it will print properly on 363138032Speter a duplex printer. From Matthew Black of Cal State University, 363238032Speter Long Beach. 363338032Speter 363464562Sgshapiro8.8.4/8.8.4 1996/12/02 363538032Speter SECURITY: under some circumstances, an attacker could get additional 363638032Speter permissions by hard linking to files that were group 363738032Speter writable by the attacker. The solution is to disallow any 363838032Speter files that have hard links -- this will affect .forward, 363938032Speter :include:, and output files. Problem noted by Terry 364038032Speter Kyriacopoulos of Interlog Internet Services. As a 364138032Speter workaround, set UnsafeGroupWrites -- always a good idea. 364238032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 364338032Speter is, it is possible to do a denial-of-service attack on 364438032Speter MX hosts that rely on the use of the null MX list. There 364538032Speter is no danger if you have this option turned off (the default). 364638032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 364738032Speter unsafe. I know of no specific attack against this, although 364838032Speter a denial-of-service attack is probably possible, but in theory 364938032Speter you should not be able to safely tweak anything that affects 365038032Speter the permissions that are used when mail is delivered. 365138032Speter Purgestat could go into an infinite loop if one of the host status 365238032Speter directories somehow became empty. Problem noted by Roy 365338032Speter Mongiovi of Georgia Tech. 365438032Speter Processes got "lost" when counting children due to a race condition. 365538032Speter This caused "proc_list_probe: lost pid" messages to be logged. 365638032Speter Problem noted by several people. 365738032Speter On systems with System V SIGCLD child signal semantics (notably AIX 365838032Speter and HP-UX), mail transactions would print the message "451 365938032Speter SMTP-MAIL: lost child: No child processes". Problem noted 366038032Speter by several people. 366138032Speter Miscellaneous compiler warnings on picky compilers (or when setting 366238032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 366338032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 366438032Speter not be persistent between runs, since they are based on the 366538032Speter message rather than the host. Problem noted by Matt Dillon 366638032Speter of Best Internet Communications. 366738032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 366838032Speter of NCR (a.k.a., AT&T Global Information Solutions). 366938032Speter Avoid the possibility of having a child daemon run to completion 367038032Speter (including closing the SMTP socket) before the parent has 367138032Speter had a chance to close the socket; this can cause the parent 367238032Speter to hang for a long time waiting for the socket to drain. 367338032Speter Patch from Don Lewis of TDK Semiconductor. 367438032Speter If the fork() failed in a queue run, the queue runners would not be 367538032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 367638032Speter Some error conditions in ETRN could cause output without an SMTP 367738032Speter status code. Problem noted by Don Lewis. 367838032Speter Multiple :maildrop addresses in the user database didn't work properly. 367938032Speter Patch from Roy Mongiovi of Georgia Tech. 368038032Speter Add ".db" automatically onto any user database spec that does not 368138032Speter already have it; this is for consistency with makemap, the 368238032Speter K line, and the documentation. Inconsistency pointed out 368338032Speter by Roy Mongiovi. 368438032Speter Allow sendmail to be properly called in nohup mode. Patch from 368538032Speter Kyle Jones of UUNET. 368638032Speter Change ETRN to ignore but still update host status files; previously 368738032Speter it would ignore them and not save the updated status, which 368838032Speter caused stale information to be maintained. Based on a patch 368938032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 369038032Speter ETRN ignore the MinQueueAge option. 369138032Speter Patch long term host status to recover more gracefully from an empty 369238032Speter host status file condition. Patch from NAKAMURA Motonori 369338032Speter of Kyoto University. 369438032Speter Several patches to signal handling code to fix potential race 369538032Speter conditions from Don Lewis. 369638032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 369738032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 369838032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 369938032Speter compile flag; use NETINET instead. Solution based on a 370038032Speter patch from Bryan Costales. 370138032Speter PORTABILITY FIXES: 370238032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 370338032Speter /etc/security/passwd file when called as root. This 370438032Speter is very slow on some systems. To speed it up, use the 370538032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 370638032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 370738032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 370838032Speter Glicker of Burrelle's Information Service. 370938032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 371038032Speter from Makoto MATSUSHITA of Osaka University. 371138032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 371238032Speter Leeds University and SASABE Tetsuro of the University 371338032Speter of Tokyo. 371438032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 371538032Speter Services, Inc. 371638032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 371738032Speter I believe this to have only been a problem if you 371838032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 371938032Speter to stick with /etc/sendmail.cf as your One True Path. 372038032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 372138032Speter Martin Laubach of the Technischen Universit�t Wien. 372238032Speter CONFIG: change default Received: line to be multiple lines rather 372338032Speter than one long one. By popular demand. 372438032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 372538032Speter from Jerome Berkman of U.C. Berkeley. 372638032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 372738032Speter to take a very long time. Problem noted by Yoshiro YONEYA 372838032Speter of NTT Software Corporation. 372938032Speter CONTRIB: add etrn.pl, contributed by John Beck. 373038032Speter NEW FILES: 373138032Speter contrib/etrn.pl 373238032Speter 373364562Sgshapiro8.8.3/8.8.3 1996/11/17 373438032Speter SECURITY: it was possible to get a root shell by lying to sendmail 373538032Speter about argv[0] and then sending it a signal. Problem noted 373638032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 373738032Speter best-of-security list. 373838032Speter Log sendmail binary version number in "Warning: .cf version level 373938032Speter (%d) exceeds program functionality (%d) message" -- this 374038032Speter should make it clearer to people that they are running 374138032Speter the wrong binary. 374238032Speter Fix a problem that occurs when you open an SMTP connection and then 374338032Speter do one or more ETRN commands followed by a MAIL command; at 374438032Speter the end of the DATA phase sendmail would incorrectly report 374538032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 374638032Speter noted by Eric Bishop of Virginia Tech. 374738032Speter When doing text-based host canonification (typically /etc/hosts 374838032Speter lookup), a null host name would match any /etc/hosts entry 374938032Speter with space at the end of the line. Problem noted by Steve 375038032Speter Hubert of the University of Washington, Seattle. 375138032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 375238032Speter Problem reported by Tom Smith of Digital Equipment Corp. 375338032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 375438032Speter size PACKETSZ (512) is not sufficient for some nameserver 375538032Speter answers containing very many resource records. The resolver 375638032Speter may also switch to TCP and retry if it detects UDP packet 375738032Speter overflow. Also, allow for the fact that the resolver 375838032Speter routines res_query and res_search return the size of the 375938032Speter *un*truncated answer in case the supplied answer buffer it 376038032Speter not big enough to accommodate the entire answer. Patch from 376138032Speter Eric Wassenaar. 376238032Speter Improvements to MaxDaemonChildren code. If you think you have too 376338032Speter many children, probe the ones you have to verify that they 376438032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 376538032Speter Also, do this probe before growing the vector of children 376638032Speter pids; this previously caused the vector to grow indefinitely 376738032Speter due to a race condition. Problem reported by Kyle Jones of 376838032Speter UUNET. 376938032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 377038032Speter O_EXLOCK to zero; this fools the map compilation code into 377138032Speter thinking that it can avoid race conditions by locking on open. 377238032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 377338032Speter Leif Erlingsson of Data Lege. 377438032Speter Always call res_init() on startup (if compiled in, of course) to 377538032Speter allow the sendmail.cf file to tweak resolver flags; without 377638032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 377738032Speter Andrew Sun of Merrill Lynch. 377838032Speter Improvements to host status printing code. Suggested by Steve Hubert 377938032Speter of the University of Washington, Seattle. 378038032Speter Change MinQueueAge option processing to do the check for the job age 378138032Speter when reading the queue file, rather than at the end; this 378238032Speter avoids parsing the addresses, which can do DNS lookups. 378338032Speter Problem noted by John Beck of InReference, Inc. 378438032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 378538032Speter properly escaped. Problem noted by Peter Nilsson of the 378638032Speter University of Linkoping. 378738032Speter In some cases, sendmail would retain root permissions during queue 378838032Speter runs even if RunAsUser was set. Problem noted by Mark 378938032Speter Thomas of Mark G. Thomas Consulting. 379038032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 379138032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 379238032Speter the envelope, and the receiving SMTP server speaks DSN, then 379338032Speter the DSN would be both generated locally and propagated to the 379438032Speter other end. 379538032Speter The U= mailer field didn't correctly extract the group id if the 379638032Speter user id was numeric. Problem noted by Kenneth Herron of 379738032Speter MCI Telecommunications Communications. 379838032Speter If a message exceeded the fixed maximum size on input, the body of 379938032Speter the message was included in the bounce. Note that this did 380038032Speter not occur if it exceeded the maximum _output_ size. Problem 380138032Speter reported by Kyle Jones of UUNET. 380238032Speter PORTABILITY FIXES: 380338032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 380438032Speter AIX4 defines to use seteuid(2) instead, which 380538032Speter works on 4.1 as well as 4.2. Problem noted by 380638032Speter H�kan Lindholm of interAF, Sweden. 380738032Speter AIX4: use tzname[] vector to determine time zone name. 380838032Speter Patch from NAKAMURA Motonori of Kyoto University. 380938032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 381038032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 381138032Speter Solaris: kstat(3k) support for retrieving the load average. 381238032Speter This adds the LA_KSTAT definition for LA_TYPE. 381338032Speter The outline of the implementation was contributed 381438032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 381538032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 381638032Speter declaration of struct rusage at the top of conf.h; 381738032Speter change it to only be included if you are using gcc, 381838032Speter which is apparently the only compiler that requires 381938032Speter it in the first place. Problem noted by Jeff 382038032Speter Earickson of Colby College. 382138032Speter IRIX: don't default to using gcc. IRIX is a civilized 382238032Speter operating system that comes with a decent compiler 382338032Speter by default. Problem noted by Barry Bouwsma and 382438032Speter Kari Hurtta. 382538032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 382638032Speter consistency with other local mailers. Inconsistency 382738032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 382838032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 382938032Speter overhead) as part of the bestmx_is_local feature, the 383038032Speter domain part was dropped from the name. Patch from Steve 383138032Speter Hubert of the University of Washington, Seattle. 383238032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 383338032Speter end up being translated to the null host name, which would 383438032Speter return any entry in /etc/hosts that had a space at the end 383538032Speter of the line. Problem noted by Steve Hubert of the 383638032Speter University of Washington, Seattle. 383738032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 383838032Speter Polytechnic Institute. 383938032Speter MAKEMAP: tweak hash and btree parameters for better performance. 384038032Speter Patch from Matt Dillon of Best Internet Communications. 384138032Speter NEW FILES: 384238032Speter src/Makefiles/Makefile.Linux.ppc 384338032Speter cf/ostype/aix4.m4 384438032Speter cf/ostype/mklinux.m4 384538032Speter 384664562Sgshapiro8.8.2/8.8.2 1996/10/18 384738032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 384838032Speter changed the code but didn't fix the problem. 384938032Speter PORTABILITY FIXES: 385038032Speter Solaris: Don't use the system getusershell(3); it can 385138032Speter apparently corrupt the heap in some circumstances. 385238032Speter Problem found by Ken Pizzini of Spry, Inc. 385338032Speter OP.ME: document several mailer flags that were accidentally omitted 385438032Speter from this document. These flags were F=d, F=j, F=R, and F=9. 385538032Speter CONFIG: no changes. 385638032Speter 385764562Sgshapiro8.8.1/8.8.1 1996/10/17 385838032Speter SECURITY: unset all environment variables that the resolver will 385938032Speter examine during queue runs and daemon mode. Problem noted 386038032Speter by Dan Bernstein of the University of Illinois at Chicago. 386138032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 386238032Speter message could overflow a buffer if it was converted back 386338032Speter to 8 bits. This caused core dumps and has the potential 386438032Speter for a remote attack. Problem first noted by Gregory Shapiro 386538032Speter of WPI. 386638032Speter Avoid duplicate deliveries of error messages on systems that don't 386738032Speter have flock(2) support. Patch from Motonori Nakamura of 386838032Speter Kyoto University. 386938032Speter Ignore null FallBackMX (V) options. If this option is null (as 387038032Speter opposed to undefined) it can cause "null signature" syserrs 387138032Speter on illegal host names. 387238032Speter If a Base64 encoded text/plain message has no trailing newline in 387338032Speter the encoded text, conversion back to 8 bits will drop the 387438032Speter final line. Problem noted by Pierre David. 387538032Speter If running with a RunAsUser, sendmail would give bogus "cannot 387638032Speter setuid" (or seteuid, or setreuid) messages on some systems. 387738032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 387838032Speter Always print error messages in -bv mode -- previously, -bv would 387938032Speter be absolutely silent on errors if the error mode was sent 388038032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 388138032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 388238032Speter term host status. This is necessary because it is common 388338032Speter to do this when you know a host has just come back up. 388438032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 388538032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 388638032Speter University of Leicester. 388738032Speter If a service (such as NIS) is specified as the last entry in the 388838032Speter service switch, but that service is not compiled in, sendmail 388938032Speter would return a temporary failure when an entry was not found 389038032Speter in the map. This caused the message to be queued instead of 389138032Speter bouncing immediately. Problem noted by Harry Edmon of the 389238032Speter University of Washington. 389338032Speter PORTABILITY FIXES: 389438032Speter Solaris 2.3 had compilation problems in conf.c. Several 389538032Speter people pointed this out. 389638032Speter NetBSD from Charles Hannum of MIT. 389738032Speter AIX4 improvements based on info from Steve Bauer of South 389838032Speter Dakota School of Mines & Technology. 389938032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 390038032Speter Patch from Gil Kloepfer Jr. 390138032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 390238032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 390338032Speter were also in $=w. Problem noted by Zoltan Basti of 390438032Speter Softec. 390538032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 390638032Speter on a patch from Eric Hagberg of Morgan Stanley. 390738032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 390838032Speter of Stanford via Robert La Ferla. 390938032Speter 391064562Sgshapiro8.8.0/8.8.0 1996/09/26 391138032Speter Under some circumstances, Bcc: headers would not be properly 391238032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 391338032Speter Log a warning if the sendmail daemon is invoked without a full 391438032Speter pathname, which prevents "kill -1" from working. I was 391538032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 391638032Speter Fix small buffer overflow. Since the data in this buffer was not 391738032Speter read externally, there was no security problem (and in fact 391838032Speter probably wouldn't really overflow on most compilers). Pointed 391938032Speter out by KIZU takashi of Osaka University. 392038032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 392138032Speter if a FallbackMXHost was specified in the configuration file 392238032Speter -- all mail would be sent to the fallback even if the original 392338032Speter host was accessible. Pointed out by Munenari Hirayama of 392438032Speter NSC (Japan). 392538032Speter A message that didn't terminate with a newline would (sometimes) not 392638032Speter have the trailing "." added properly in the SMTP dialogue, 392738032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 392838032Speter The DaemonPortOptions suboption to bind to a particular address was 392938032Speter incorrect and nonfunctional due to a misunderstanding of the 393038032Speter semantics of binding on a passive socket. Patch from 393138032Speter NIIBE Yutaka of Mitsubishi Research Institute. 393238032Speter Increase the number of MX hosts for a single name to 100 to better 393338032Speter handle the truly huge service providers such as AOL, which 393438032Speter has 13 at the moment (and climbing). In order to avoid 393538032Speter trashing memory, the buffer for all names has only been 393638032Speter slightly increased in size, to 12.8K from 10.2K -- this means 393738032Speter that if a single name had 100 MX records, the average size 393838032Speter of those records could not exceed 128 bytes. Requested by 393938032Speter Brad Knowles of America On Line. 394038032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 394138032Speter Urged by Dan Bernstein of U.C. Berkeley. 394238032Speter Print q_statdate and q_specificity in address structure debugging 394338032Speter printout. 394438032Speter Expand MCI structure flag bits for debugging output. 394538032Speter Support IPv6-style domain literals, which can have colons between 394638032Speter square braces. 394738032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 394838032Speter this is an attempt to track down a bug that one person seems 394938032Speter to be having (it may be a Solaris bug!). 395038032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 395138032Speter this caused the NOTIFY info to sometimes be lost. Problem 395238032Speter pointed out by Claus Assmann of the 395338032Speter Christian-Albrechts-University of Kiel. 395438032Speter The statistics gathered in the sendmail.st file were too high; in 395538032Speter some cases failures (e.g., user unknown or temporary failure) 395638032Speter would count as a delivery as far as the statistics were 395738032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 395838032Speter Systems that don't have flock() would not send split envelopes in 395938032Speter the initial run. Problem pointed out by Leonard Zubkoff of 396038032Speter Dandelion Digital. 396138032Speter Move buffer overflow checking -- these primarily involve distrusting 396238032Speter results that may come from NIS and DNS. 396338032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 396438032Speter include <paths.h> and hence had the wrong pathnames for a few 396538032Speter things like /var/tmp. Reported by Matthew Green. 396638032Speter Conditions were reversed for the Priority: header, resulting in all 396738032Speter values being interpreted as non-urgent except for non-urgent, 396838032Speter which was interpreted as normal. Patch from Bryan Costales. 396938032Speter The -o (optional) flag was being ignored on hash and btree maps 397038032Speter since 8.7.2. Fix from Bryan Costales. 397138032Speter Content-Types listed in class "q" will always be encoded as 397238032Speter Quoted-Printable (or more accurately, will never be encoded 397338032Speter as base64). The class can have primary types (e.g., "text") 397438032Speter or full types (e.g., "text/plain"). Based on a suggestion by 397538032Speter Marius Olafsson of the University of Iceland. 397638032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 397738032Speter dialogue) so it can be passed to programs in mailers. 397838032Speter Define ${bodytype} to be the body type (from the -B flag or the 397938032Speter BODY= ESMTP parameter) so it can be passed to programs in 398038032Speter mailers. 398138032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 398238032Speter flag is set in the mailer descriptor. Suggested by John 398338032Speter Myers of CMU. 398438032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 398538032Speter The command takes a host name; data for that host is 398638032Speter immediately (and asynchronously) flushed. Because this shares 398738032Speter the -qR implementation, other hosts may be attempted, but 398838032Speter there should be no security implications. Implementation 398938032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 399038032Speter Add three new command line flags to pass in DSN parameters: -V envid 399138032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 399238032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 399338032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 399438032Speter that the -N flag applies to all recipients; there is no way 399538032Speter to specify per-address notifications on the command line, 399638032Speter nor is there an equivalent for the ORCPT= per-address 399738032Speter parameter. 399838032Speter Restore LogLevel option to be safe (it can only be increased); 399938032Speter apparently I went into paranoid mode between 8.6 and 8.7 400038032Speter and made it unsafe. Pointed out by Dabe Murphy of the 400138032Speter University of Maryland. 400238032Speter New logging on log level 15: all SMTP traffic. Patches from 400338032Speter Andrew Gross of San Diego Supercomputer Center. 400438032Speter NetInfo property value searching code wasn't stopping when it found 400538032Speter a match. This was causing the wrong values to be found (and 400638032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 400738032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 400838032Speter out by Bill Wisner of Electronics for Imaging that you can't 400938032Speter use the bracket address form for the MAIL_HUB macro, since 401038032Speter that causes the brackets to remain in the envelope recipient 401138032Speter address used for delivery. The simple fix (stripping off the 401238032Speter brackets in the config file) breaks the use of IP literal 401338032Speter addresses. This flag will solve that problem. 401438032Speter Add MustQuoteChars option. This is a list of characters that must 401538032Speter be quoted if they are found in the phrase part of an address 401638032Speter (that is, the full name part). The characters @,;:\()[] are 401738032Speter always in this list and cannot be removed. The default is 401838032Speter this list plus . and ' to match RFC 822. 401938032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 402038032Speter that do not include a host name for back compatibility with 402138032Speter some stupid SMTP clients. Setting this violates RFC 1123 402238032Speter section 5.2.5. 402338032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 402438032Speter rejecting connections if it has more than this many 402538032Speter outstanding children accepting mail. Note that you may 402638032Speter see more processes than this because of outgoing mail; this 402738032Speter is for incoming connections only. 402838032Speter Add ConnectionRateThrottle option. If set to a positive value, the 402938032Speter number of incoming SMTP connections that will be permitted 403038032Speter in a single second is limited to this number. Connections are 403138032Speter not refused during this time, just deferred. The intent is to 403238032Speter flatten out demand so that load average limiting can kick in. 403338032Speter It is less radical than MaxDaemonChildren, which will stop 403438032Speter accepting connections even if all the connections are idle 403538032Speter (e.g., due to connection caching). 403638032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 403738032Speter specifies how long cached information about the state of a 403838032Speter host will be kept before they are considered stale and the 403938032Speter host is retried. If you are using persistent host status 404038032Speter (i.e., the HostStatusDirectory option is set) this will apply 404138032Speter between runs; otherwise, it applies only within a single queue 404238032Speter run and hence is useful only for hosts that have large queues 404338032Speter that take a very long time to run. 404438032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 404538032Speter into being a single line even if they had newlines in them 404638032Speter when read. This is to get around a botch in Lotus Notes. 404738032Speter Text class maps were totally broken -- if you ever retrieved the last 404838032Speter item in a table it would be truncated. Problem noted by 404938032Speter Gregory Neil Shapiro of WPI. 405038032Speter Extend the lines printed by the mailq command (== the -bp flag) when 405138032Speter -v is given to 120 characters; this allows more information 405238032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 405338032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 405438032Speter this was treated as end-of-input. Problem noted by Bryan 405538032Speter Costales. 405638032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 405738032Speter to the queue file. Fix from John Hughes of Atlantic 405838032Speter Technologies, Inc. 405938032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 406038032Speter if this happens in a queue run it can cause nasty delays. 406138032Speter Problem noted by Mark Horton of AT&T. 406238032Speter If userdb entries pointed to userdb entries, and there were multiple 406338032Speter values for a given key, the database cursor would get 406438032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 406538032Speter of Georgia Tech. Fixed by reading all the values and creating 406638032Speter a comma-separated list; thus, the -v output will be somewhat 406738032Speter different for this case. 406838032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 406938032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 407038032Speter of Stanford University. 407138032Speter When envelopes were split due to aliases with owner- aliases, and 407238032Speter there was some error on one of the lists, more than one of 407338032Speter the owners would get the message. Problem pointed out by 407438032Speter Roy Mongiovi of Georgia Tech. 407538032Speter Detect excessive recursion in macro expansions, e.g., $X defined 407638032Speter in terms of $Y which is defined in terms of $X. Problem 407738032Speter noted by Bryan Costales; patch from Eric Wassenaar. 407838032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 407938032Speter some cases get trashed causing bogus From_ lines. Fix from 408038032Speter Kyle Jones of UUNET. 408138032Speter When doing load average initialization, if the nlist call for avenrun 408238032Speter failed, the second and subsequent lookups wouldn't notice 408338032Speter that fact causing bogus load averages to be returned. Noted 408438032Speter by Casper Dik of Sun Holland. 408538032Speter Fix problem with incompatibility with some versions of inet_aton that 408638032Speter have changed the return value to unsigned, so a check for an 408738032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 408838032Speter This could cause mail to addresses such as [foo.com] to bounce 408938032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 409038032Speter Pasteur Institute. 409138032Speter DSNs were inconsistent if a failure occurred during the DATA phase 409238032Speter rather than the RCPT phase: the Action: would be correct, but 409338032Speter the detailed status information would be wrong. Problem noted 409438032Speter by Bob Snyder of General Electric Company. 409538032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 409638032Speter that this is the initial MUA->MTA submission. The flag current 409738032Speter does nothing, but in future releases (when MUAs start using 409838032Speter these flags) it will probably turn on things like DNS 409938032Speter canonification. 410038032Speter Default end-of-line string (E= specification on mailer [M] lines) 410138032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 410238032Speter mailers. 410338032Speter Change the internal definition for the *file* and *include* mailers 410438032Speter to have $u in the argument vectors so that they aren't 410538032Speter misinterpreted as SMTP mailers and thus use \r\n line 410638032Speter termination. This will affect anyone who has redefined 410738032Speter either of these in their configuration file. 410838032Speter Don't assume that IDENT servers close the connection after a query; 410938032Speter responses can be newline terminated. From Terry Kennedy of 411038032Speter St. Peter's College. 411138032Speter Avoid core dumps on erroneous configuration files that have 411238032Speter $#mailer with nothing following. From Bryan Costales. 411338032Speter Avoid null pointer dereference with high debug values in unlockqueue. 411438032Speter Fix from Randy Martin of Clemson University. 411538032Speter Fix possible buffer overrun when expanding very large macros. Fix 411638032Speter from Kyle Jones of UUNET. 411738032Speter After 25 EXPN or VRFY commands, start pausing for a second before 411838032Speter processing each one. This avoids a certain form of denial 411938032Speter of service attack. Potential attack pointed out by Bryan 412038032Speter Costales. 412138032Speter Allow new named (not numbered!) config file rules to do validity 412238032Speter checking on SMTP arguments: check_mail for MAIL commands and 412338032Speter check_rcpt for RCPT commands. These rulesets can do anything 412438032Speter they want; their result is ignored unless they resolve to the 412538032Speter $#error mailer, in which case the indicated message is printed 412638032Speter and the command is rejected. Similarly, the check_compat 412738032Speter ruleset is called before delivery with "from_addr $| to_addr" 412838032Speter (the $| is a meta-symbol used to separate the two addresses); 412938032Speter it can give a "this sender can't send to this recipient" 413038032Speter notification. Note that this patch allows $| to stand alone 413138032Speter in rulesets. 413238032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 413338032Speter that have the name, IP address, and port number (respectively) 413438032Speter of the SMTP client (that is, the entity at the other end of 413538032Speter the connection. These can be used in (e.g.) check_rcpt to 413638032Speter verify that someone isn't trying to relay mail through your 413738032Speter host inappropriately. Be sure to use the deferred evaluation 413838032Speter form, for example $&{client_name}, to avoid having these bound 413938032Speter when sendmail reads the configuration file. 414038032Speter Add new config file rule check_relay to check the incoming connection 414138032Speter information. Like check_compat, it is passed the host name 414238032Speter and host address separated by $| and can reject connections 414338032Speter on that basis. 414438032Speter Allow IDA-style recursive function calls. Code contributed by Mark 414538032Speter Lovell and Paul Vixie. 414638032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 414738032Speter a virtual UUCP address using either a domain address or the $k 414838032Speter macro. Based on code contributed by Mark Lovell and Paul 414938032Speter Vixie. 415038032Speter Add Stanford LDAP map. Requires special libraries that are not 415138032Speter included with sendmail. Contributed by Booker C. Bense 415238032Speter <bbense@networking.stanford.edu>; contact him for support. 415338032Speter See also the src/READ_ME file. 415438032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 415538032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 415638032Speter only for debugging deep bits of code where it is important to 415738032Speter distinguish between the single-character metasymbol $+ and the 415838032Speter two characters $, +. 415938032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 416038032Speter debug_dumpstate. 416138032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 416238032Speter files that are group writable are considered "unsafe" -- that 416338032Speter is, programs and files referenced from such files are not 416438032Speter valid recipients. 416538032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 416638032Speter name that was not in DNS or was a domain-literal. Problem 416738032Speter noted by Tom May. 416838032Speter Change the introduction to error messages to more clearly delineate 416938032Speter permanent from temporary failures; if both existed in a 417038032Speter single message it could be confusing. Suggested by John 417138032Speter Beck of InReference, Inc. 417238032Speter The IngoreDot (i) option didn't work for lines that were terminated 417338032Speter with CRLF. Problem noted by Ted Stockwell of Secure 417438032Speter Computing Corporation. 417538032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 417638032Speter message headers. Problem reported by Matt Dillon of Best 417738032Speter Internet Communications. 417838032Speter Check for bogus characters in the 0200-0237 range; since these are 417938032Speter used internally, very strange errors can occur if those 418038032Speter characters appear in headers. Problem noted by Anders Gertz 418138032Speter of Lysator. 418238032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 418338032Speter recipient mailer has the F=9 flag set, and only works on 418438032Speter text/plain body types. Code contributed by Marius Olafsson 418538032Speter of the University of Iceland. 418638032Speter Special case "postmaster" name so that it is always treated as lower 418738032Speter case in alias files regardless of configuration settings; 418838032Speter this prevents some potential problems where "Postmaster" or 418938032Speter "POSTMASTER" might not match "postmaster". In most cases 419038032Speter this change is a no-op. 419138032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 419238032Speter Costales. 419338032Speter The -a map flag was ignored for dequote maps. Problem noted by 419438032Speter Bryan Costales. 419538032Speter Fix core dump when a lookup of a class "prog" map returns no 419638032Speter response. Patch from Bryan Costales. 419738032Speter Log instances where sendmail is deferring or rejecting connections 419838032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 419938032Speter Include port number in process title for network daemons. Suggested 420038032Speter by Kyle Jones of UUNET. 420138032Speter Send ``double bounces'' (errors that occur when sending an error 420238032Speter message) to the address indicated in the DoubleBounceAddress 420338032Speter option (default: postmaster). Previously they were always 420438032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 420538032Speter Add new mode, -bD, that acts like -bd in all respects except that 420638032Speter it runs in foreground. This is useful for using with a 420738032Speter wrapper that "watches" system services. Suggested by Kyle 420838032Speter Jones of UUNET. 420938032Speter Fix botch in spacing around (parenthesized) comments in addresses 421038032Speter when the comment comes before the address. Patch from 421138032Speter Motonori Nakamura of Kyoto University. 421238032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 421338032Speter that are being bounced to postmaster, rather than "Returned 421438032Speter mail". This permits the person who is postmaster more 421538032Speter easily determine what messages are to their role as 421638032Speter postmaster versus bounces to mail they actually sent. Based 421738032Speter on a suggestion by Motonori Nakamura. 421838032Speter Add new value "time" for QueueSortOrder option; this causes the queue 421938032Speter to be sorted strictly by the time of submission. Note that 422043730Speter this can cause very bad behavior over slow lines (because 422138032Speter large jobs will tend to delay small jobs) and on nodes with 422238032Speter heavy traffic (because old things in the queue for hosts that 422338032Speter are down delay processing of new jobs). Also, this does not 422438032Speter guarantee that jobs will be delivered in submission order 422538032Speter unless you also set DeliveryMode=queue. In general, it should 422638032Speter probably only be used on the command line, and only in 422738032Speter conjunction with -qRhost.domain. In fact, there are very few 422838032Speter cases where it should be used at all. Based on an 422938032Speter implementation by Motonori Nakamura. 423038032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 423138032Speter the same manner as other rulesets. Previously a temporary 423238032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 423338032Speter of Stanford University. 423438032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 423538032Speter 5yz (permanent failure) code. The next MX host will still be 423638032Speter tried if the connection cannot be opened in the first place 423738032Speter or if the MAIL command returns a 4yz (temporary failure) code. 423838032Speter (It's hard to know what to do here, since neither RFC 974 nor 423938032Speter RFC 1123 specify when to proceed to the next MX host.) 424038032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 424138032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 424238032Speter This causes map lookups that get a temporary failure (e.g., 424338032Speter name server failure) to _not_ defer the delivery of the 424438032Speter message. This should only be used if your configuration file 424538032Speter is prepared to do something sensible in this case. Based on 424638032Speter an idea by Gregory Shapiro of WPI. 424738032Speter Fix problem finding network interface addresses. Patch from 424838032Speter Motonori Nakamura. 424938032Speter Don't reject qf entries that are not owned by your effective uid if 425038032Speter you are not running setuid; this makes management of certain 425138032Speter kinds of firewall setups difficult. Patch suggested by 425238032Speter Eamonn Coleman of Qualcomm. 425338032Speter Add persistent host status. This keeps the information normally 425438032Speter maintained within a single queue run in disk files that are 425538032Speter shared between sendmail instances. The HostStatusDirectory 425638032Speter is the directory in which the information is maintained. If 425738032Speter not set, persistent host status is turned off. If not a full 425838032Speter pathname, it is relative to the queue directory. A common 425938032Speter value is ".hoststat". 426038032Speter There are also two new operation modes: 426138032Speter * -bh prints the status of hosts that have had recent 426238032Speter connections. 426338032Speter * -bH purges the host statuses. No attempt is made to save 426438032Speter recent status information. 426538032Speter This feature was originally written by Paul Vixie of Vixie 426638032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 426738032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 426838032Speter with my insistence that things fit cleanly into the V8 426938032Speter framework is gratefully appreciated. 427038032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 427138032Speter operate). Avoids letting two sendmails on the local machine 427264562Sgshapiro open connections to the same remote host at the same time. 427338032Speter This reduces load on the other machine, but can cause mail to 427438032Speter be delayed (for example, if one sendmail is delivering a huge 427538032Speter message, other sendmails won't be able to send even small 427638032Speter messages). Also, it requires another file descriptor (for the 427738032Speter lock file) per connection, so you may have to reduce 427838032Speter ConnectionCacheSize to avoid running out of per-process 427938032Speter file descriptors. Based on the persistent host status code 428038032Speter contributed by Paul Vixie and Mark Lovell. 428138032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 428238032Speter SafeFileEnvironment option is set. Problem noted by Bryan 428338032Speter Costales. 428438032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 428538032Speter file. Problem noted by Bryan Costales. 428638032Speter If a job was aborted using the interrupt signal (e.g., control-C from 428738032Speter the keyboard), on some occasions an empty df file would be 428838032Speter left around; these would collect in the queue directory. 428938032Speter Problem noted by Bryan Costales. 429038032Speter Change the makesendmail script to enhance the search for Makefiles 429138032Speter based on release number. For example, on SunOS 5.5.1, it will 429238032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 429338032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 429438032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 429538032Speter Webmasters. 429638032Speter When creating maps using "newaliases", always map the keys to lower 429738032Speter case when creating the map unless the -f flag is specified on 429838032Speter the map itself. Previously this was done based on the F=u 429938032Speter flag in the local mailer, which meant you could create aliases 430038032Speter that you could never access. Problem noted by Bob Wu of DEC. 430138032Speter When a job was read from the queue, the bits causing notification on 430238032Speter failure or delay were always set. This caused those 430338032Speter notifications to be sent even if NOTIFY=NEVER had been 430438032Speter specified. Problem noted by Steve Hubert of the University 430538032Speter of Washington, Seattle. 430638032Speter Add new configurable routine validate_connection (in conf.c). This 430738032Speter lets you decide if you are willing to accept traffic from 430838032Speter this host. If it returns FALSE, all SMTP commands will return 430938032Speter "550 Access denied". -DTCPWRAPPERS will include support for 431038032Speter TCP wrappers; you will need to add -lwrap to the link line. 431138032Speter (See src/READ_ME for details.) 431238032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 431338032Speter bounces. Some people seemed to think that this could be 431438032Speter confusing (even though it is true). Suggested by Motonori 431538032Speter Nakamura. 431638032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 431738032Speter user early in processing to avoid potential security problems. 431838032Speter However, this means that all .forward and :include: files must 431938032Speter be readable by that user, and all files to be written must be 432038032Speter writable by that user and all programs will be executed by that 432138032Speter user. It is also incompatible with the SafeFileEnvironment 432238032Speter option. In other words, it may not actually add much to 432338032Speter security. However, it should be useful on firewalls and other 432438032Speter places where users don't have accounts and the aliases file is 432538032Speter well constrained. 432638032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 432738032Speter only on the first attempt to delivery to an address. It could 432838032Speter be set to be lower than Timeout.connect on the principle that 432938032Speter the mail should go through quickly to responsive hosts; less 433038032Speter responsive hosts get to wait for the next queue run. 433138032Speter Fix a problem on Solaris that occasionally causes programs 433238032Speter (such as vacation) to hang with their standard input connected 433338032Speter to a UDP port. It also created some signal handling problems. 433438032Speter The problems turned out to be an interaction between vfork(2) 433538032Speter and some of the libraries, particularly NIS/NIS+. I am 433638032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 433738032Speter Change user class map to do the same matching that actual delivery 433838032Speter will do instead of just a /etc/passwd lookup. This adds 433938032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 434038032Speter The Timeout.* options are not safe -- they can be used to create a 434138032Speter denial-of-service attack. Problem noted by Christophe 434238032Speter Wolfhugel. 434343730Speter Don't send PostmasterCopy messages in the event of a "delayed" 434438032Speter notification. Suggested by Barry Bouwsma. 434538032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 434638032Speter option is set, since this disables VERB mode. Suggested 434738032Speter by John Hawkinson of MIT. 434838032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 434938032Speter by Motonori Nakamura of Kyoto University. 435038032Speter Only queue messages on transient .forward open failures if there 435143730Speter were no successful opens. The previous behavior caused it 435238032Speter to queue even if a "fall back" .forward was found. Problem 435338032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 435438032Speter and Computer Science (DISCS), NUS, Singapore. 435538032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 435638032Speter is bouncing because of a MIME error during 8->7 bit conversion; 435738032Speter the encapsulated message will bounce again, causing a loop. 435838032Speter Problem noted by Steve Hubert of the University of Washington. 435938032Speter Create xf (transcript) files using the TempFileMode option value 436038032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 436138032Speter National University of Singapore. 436238032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 436338032Speter detect cases where DefaultUid is set to something that the 436438032Speter system can't cope with. 436538032Speter PORTABILITY FIXES: 436638032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 436738032Speter Atlas International. 436838032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 436938032Speter <bicknell@ufp.org>. 437038032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 437138032Speter work on the first recipient of a message due to a 437238032Speter bug in the getpwent family.

Based on a patch from Randall 441538032Speter Winchester of the University of Maryland. 441638032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 441738032Speter Robert La Ferla of Hot Software. 441838032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 441938032Speter (where "code" is an exit status) on domains (previously 442038032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 442138032Speter Foundation. 442238032Speter CONFIG: hooks for IPv6-style domain literals. 442338032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 442438032Speter if it is undefined the AliasFile option is never set; this 442538032Speter should be transparent for most everyone. Suggested by John 442638032Speter Myers of CMU. 442738032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 442838032Speter domain listed in $=w is masqueraded. With it, only those 442938032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 443038032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 443138032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 443238032Speter hosts under those domains as well as the domain headers 443338032Speter themselves. For example, if a configuration had 443438032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 443538032Speter foo.com would be masqueraded; with it, *.foo.com would be 443638032Speter masqueraded as well. Based on an implementation by Richard 443738032Speter (Pug) Bainter of U. Texas. 443838032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 443938032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 444038032Speter Keys are user names; values are outgoing mail addresses. Yes, 444138032Speter this does overlap with the user database, and figuring out 444238032Speter just when to use which one may be tricky. Based on code 444338032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 444438032Speter from Per Hedeland of Ericsson. 444538032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 444638032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 444738032Speter Keys are either fully qualified addresses or just the host 444838032Speter part (with the @ sign). For example, a table containing: 444938032Speter info@foo.com foo-info 445038032Speter info@bar.com bar-info 445138032Speter @baz.org jane@elsewhere.net 445238032Speter would send all mail destined for info@foo.com to foo-info 445338032Speter (which is presumably an alias), mail addressed to info@bar.com 445438032Speter to bar-info, and anything addressed to anyone at baz.org will 445538032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 445638032Speter and baz.org must all be in $=w. Based on discussions with 445738032Speter a great many people. 445838032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 445938032Speter Suggested by Richard Bainter. 446038032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 446138032Speter "fax" mailer. 446238032Speter CONFIG: allow mailertable entries to resolve to local:user; this 446338032Speter passes the original user@host in to procmail-style local 446438032Speter mailers as the "detail" information to allow them to do 446538032Speter additional clever processing. From Joe Pruett of 446638032Speter Teleport Corporation. Delivery to the original user can 446738032Speter be done by specifying "local:" (with nothing after the colon). 446838032Speter CONFIG: allow any context that takes "mailer:domain" to also take 446938032Speter "mailer:user@domain" to force mailing to the given user; 447038032Speter "local:user" can also be used to do local delivery. This 447138032Speter applies on *_RELAY and in the mailertable entries. Based 447238032Speter on a suggestion by Ribert Kiessling of Easynet. 447338032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 447438032Speter limits the possible domains; this reduces the number of DNS 447538032Speter lookups required to support this feature. For example, 447638032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 447738032Speter to domains under my.site.com. Code contributed by Anthony 447838032Speter Thyssen <anthony@cit.gu.edu.au>. 447938032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 448038032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 448138032Speter of WPI. 448238032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 448338032Speter event you have to define local mailers. Suggested by 448438032Speter Gregory Shapiro of WPI. 448538032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 448638032Speter be misinterpreted as a list:...; syntax. Based on a patch by 448738032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 448838032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 448938032Speter remotely connected. The address host!user was being 449038032Speter converted to host!user@thishost instead of host!user@uurelay. 449138032Speter Problem noted by William Gianopoulos of Raytheon Company. 449238032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 449338032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 449438032Speter "User has moved"; the former wording was confusing if the 449538032Speter new address is still on the local host. Based on a suggestion 449638032Speter by Andreas Luik. 449738032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 449838032Speter However, the class is not pre-initialized to contain root. 449938032Speter Suggested by Gregory Neil Shapiro. 450038032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 450138032Speter Wolfhugel. 450238032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 450338032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 450438032Speter well: this produces a slightly different mailbox format (no 450538032Speter Content-Length: headers), file ownerships and modes are 450638032Speter different (not owned by group mail; mode 600 instead of 660), 450738032Speter and the local mailer flags will have to be tweaked (make them 450838032Speter match bsd4.4) in order to use this mailer. Patches from Paul 450938032Speter Hammann of the Missouri Research and Education Network. 451038032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 451138032Speter was a delivery error, such as if the ownership on the file 451238032Speter was wrong or the mode changed between the initial stat and 451338032Speter the open. Problem reported by William Colburn of the New 451438032Speter Mexico Institute of Mining and Technology. 451538032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 451638032Speter Costales. 451738032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 451838032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 451938032Speter honored. Fix from Michael Scott Shappe. 452038032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 452138032Speter NEW FILES: 452238032Speter src/Makefiles/Makefile.AIX.2 452338032Speter src/Makefiles/Makefile.IRIX.6.2 452438032Speter src/Makefiles/Makefile.maxion 452538032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 452638032Speter src/Makefiles/Makefile.SCO.5.x 452738032Speter src/Makefiles/Makefile.UXPDSV20 452838032Speter mailstats/mailstats.8 452938032Speter praliases/praliases.8 453038032Speter cf/cf/generic-nextstep3.3.mc 453138032Speter cf/feature/genericstable.m4 453238032Speter cf/feature/limited_masquerade.m4 453338032Speter cf/feature/masquerade_entire_domain.m4 453438032Speter cf/feature/virtusertable.m4 453538032Speter cf/ostype/aix2.m4 453638032Speter cf/ostype/altos.m4 453738032Speter cf/ostype/maxion.m4 453838032Speter cf/ostype/solaris2.ml.m4 453938032Speter cf/ostype/uxpds.m4 454038032Speter contrib/re-mqueue.pl 454138032Speter DELETED FILES: 454238032Speter src/Makefiles/Makefile.Solaris 454338032Speter contrib/xla/README 454438032Speter contrib/xla/xla.c 454538032Speter RENAMED FILES: 454638032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 454738032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 454838032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 454938032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 455038032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 455138032Speter 455264562Sgshapiro8.7.6/8.7.3 1996/09/17 455338032Speter SECURITY: It is possible to force getpwuid to fail when writing the 455438032Speter queue file, causing sendmail to fall back to running programs 455538032Speter as the default user. This is not exploitable from off-site. 455638032Speter Workarounds include using a unique user for the DefaultUser 455738032Speter (old u & g options) and using smrsh as the local shell. 455838032Speter SECURITY: fix some buffer overruns; in at least one case this allows 455938032Speter a local user to get root. This is not known to be exploitable 456038032Speter from off-site. The workaround is to disable chfn(1) commands. 456138032Speter 456264562Sgshapiro8.7.5/8.7.3 1996/03/04 456338032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 456438032Speter in some case cause connections to hang or messages to have 456538032Speter extra spaces in odd places. Patch from Eric Wassenaar; 456638032Speter reports from Eric Hall of Chiron Corporation, Stephen 456738032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 456838032Speter and others. 456938032Speter 457064562Sgshapiro8.7.4/8.7.3 1996/02/18 457138032Speter SECURITY: In some cases it was still possible for an attacker to 457238032Speter insert newlines into a queue file, thus allowing access to 457338032Speter any user (except root). 457438032Speter CONFIG: no changes -- it is not a bug that the configuration 457538032Speter version number is unchanged. 457638032Speter 457764562Sgshapiro8.7.3/8.7.3 1995/12/03 457838032Speter Fix botch in name server timeout in RCPT code; this problem caused 457938032Speter two responses in SMTP, which breaks things horribly. Fix 458038032Speter from Gregory Neil Shapiro of WPI. 458138032Speter Verify that L= value on M lines cannot be negative, which could cause 458238032Speter negative array subscripting. Not a security problem since 458338032Speter this has to be in the config file, but it could have caused 458438032Speter core dumps. Pointed out by Bryan Costales. 458538032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 458638032Speter Costales. 458738032Speter PORTABILITY FIXES: 458838032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 458938032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 459038032Speter order. Tweak it to work properly. Based on fixes 459138032Speter from Fletcher Mattox of UTexas and Betty Lee of 459238032Speter Stanford University. 459338032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 459438032Speter Deficiency pointed out by Bryan Costales of ICSI. 459538032Speter 459664562Sgshapiro8.7.2/8.7.2 1995/11/19 459738032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 459838032Speter OperatorChars, and UnixFromLine options. They were not 459938032Speter properly repaired in 8.7.1. 460038032Speter Completely delete the Bcc: header if and only if there are other 460138032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 460238032Speter last being a historic botch, of course). If Bcc: is the 460338032Speter only recipient header in the message, its value is tossed, 460443730Speter but the header name is kept. The old behavior (always keep 460538032Speter the header name and toss the value) allowed primary recipients 460638032Speter to see that a Bcc: went to _someone_. 460738032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 460838032Speter sender to <address> using -f'' syslog messages. Suggested 460938032Speter by Kari Hurtta. 461038032Speter If a sequence or switch map lookup entry gets a tempfail but then 461138032Speter continues on to another map type, but the name is not found, 461238032Speter return a temporary failure from the sequence or switch map. 461338032Speter For example, if hosts search ``dns files'' and DNS fails 461438032Speter with a tempfail, the hosts map will go on and search files, 461538032Speter but if it fails the whole thing should be a tempfail, not 461638032Speter a permanent (host unknown) failure, even though that is the 461738032Speter failure in the hosts.files map. This error caused hard 461838032Speter bounces when it should have requeued. 461938032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 462038032Speter owned by bar mode 700 and inbox being setuid bar stopped 462138032Speter working properly due to excessive paranoia. Pointed out by 462238032Speter John Hawkinson of Panix. 462338032Speter An SMTP RCPT command referencing a host that gave a nameserver 462438032Speter timeout would return a 451 command (8.6 accepted it and 462543730Speter queued it locally). Revert to the 8.6 behavior in order 462638032Speter to simplify queue management for clustered systems. Suggested 462738032Speter by Gregory Neil Shapiro of WPI. The same problem could break 462838032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 462938032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 463038032Speter Infobiogen. 463138032Speter Fix possible buffer overflow in munchstring(). This was not a security 463238032Speter problem because you couldn't specify any argument to this 463338032Speter without first giving up root privileges, but it is still a 463438032Speter good idea to avoid future problems. Problem noted by John 463538032Speter Hawkinson and Sam Hartman of MIT. 463638032Speter ``452 Out of disk space for temp file'' messages weren't being 463738032Speter printed. Fix from David Perlin of Nanosoft. 463843730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 463938032Speter is not set, since this is required to get the actual DSNs 464038032Speter created. Problem pointed out by John Gardiner Myers of CMU. 464138032Speter Log permission problems that cause .forward and :include: files to 464238032Speter be untrusted or ignored on log level 12 and higher. Suggested 464338032Speter by Randy Martin of Clemson University. 464438032Speter Allow user ids in U= clauses of M lines to have hyphens and 464538032Speter underscores. 464638032Speter Fix overcounting of recipients -- only happened when sending to an 464738032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 464838032Speter of Systems and Computer Technology Corporation. 464938032Speter If a message is sent to an address that fails, the error message that 465038032Speter is returned could show some extraneous "success" information 465138032Speter included even if the user did not request success notification, 465238032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 465338032Speter Config files that had no AliasFile definition were defaulting to 465438032Speter using /etc/aliases; this caused problems with nullclient 465538032Speter configurations. Change it back to the 8.6 semantics of 465638032Speter having no local alias file unless it is declared. Problem 465738032Speter noted by Charles Karney of Princeton University. 465838032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 465938032Speter Costales of ICSI. 466038032Speter Map lookups of class "userdb" maps were always case sensitive; they 466138032Speter should be controlled by the -f flag like other maps. Pointed 466238032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 466338032Speter Fix problem that caused some addresses to be passed through ruleset 5 466438032Speter even when they were tagged as "sticky" by prefixing the 466538032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 466638032Speter Technological University. 466738032Speter When converting a message to Quoted-Printable, prevent any lines with 466838032Speter dots alone on a line by themselves. This is because of the 466938032Speter preponderance of broken mailers that still get this wrong. 467038032Speter Code contributed by Per Hedeland of Ericsson. 467138032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 467238032Speter out by Bjart Kvarme of USIT/UiO (Norway). 467338032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 467438032Speter Requested by Allan Johannesen. 467538032Speter Delete check for text format of alias files -- it should be legal 467638032Speter to have the database format of the alias files without the 467738032Speter text version. Problem pointed out by Joe Rhett of Navigist, 467838032Speter Inc. 467938032Speter If "Ot" was specified with no value, the TZ variable was not properly 468038032Speter imported from the environment. Pointed out by Frank Crawford 468138032Speter <frank@ansto.gov.au>. 468238032Speter Some architectures core dumped on "program" maps that didn't have 468338032Speter extra arguments. Patch from Booker C. Bense of Stanford 468438032Speter University. 468538032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 468638032Speter the parent should do this. Fix from Brian Coan of the 468738032Speter Association for Progressive Communications. 468838032Speter If MinQueueAge was set and a message was considered but not run 468938032Speter during a queue run and the Timeout.queuereturn interval was 469038032Speter reached, a "timed out" error message would be returned that 469138032Speter didn't include the failed address (and claimed to be a warning 469238032Speter even though it was fatal). The fix is to not return such 469338032Speter messages until they are actually tried, i.e., in the next 469438032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 469538032Speter SINTEF RUNIT, Oslo. 469638032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 469738032Speter that have the hes_getmailhost() routine.

Bug 474438032Speter pointed out by John Hawkinson of MIT. 474538032Speter Fix strange case of an executable called by a program map that 474638032Speter returns a value but also a non-zero exit status; this 474738032Speter would give contradictory results in the higher level; in 474838032Speter particular, the default clause in the map lookup would be 474938032Speter ignored. Change to ignore the value if the program returns 475038032Speter non-zero exit status. From Tom Moore of AT&T GIS. 475138032Speter Shorten parameters passed to syslog() in some contexts to avoid a 475238032Speter bug in many vendors' implementations of that routine. Although 475338032Speter this isn't really a bug in sendmail per se, and my solution 475438032Speter has to assume that syslog() has at least a 1K buffer size 475538032Speter internally (I know some vendors have shortened this 475638032Speter dramatically -- they're on their own), sendmail is a popular 475738032Speter target. Also, limit the size of %s arguments in sprintf. 475838032Speter These both have possible security implications. Solutions 475938032Speter suggested by Casper Dik of Sun's Network Security Group 476038032Speter (Holland), Mark Seiden, and others. 476138032Speter Fix a problem that might cause a non-standard -B (body type) 476238032Speter parameter to be passed to the next server with undefined 476338032Speter results. This could have security implications. 476438032Speter If a filesystem was at > 100% utilization, the freediskspace() 476538032Speter routine incorrectly returned an error rather than zero. 476638032Speter Problem noted by G. Paul Ziemba of Alantec. 476738032Speter Change MX sort order so that local hostnames (those in $=w) always 476838032Speter sort first within a given preference. This forces the bestmx 476938032Speter map to always return the local host first, if it is included 477038032Speter in the list of highest priority MX records. From K. Robert 477138032Speter Elz. 477238032Speter Avoid some possible null pointer dereferences. Fixes from Randy 477338032Speter Martin <WOLF@CLEMSON.EDU> 477438032Speter When sendmail starts up on systems that have no fully qualified 477538032Speter domain name (FQDN) anywhere in the first matching host map 477638032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 477738032Speter sendmail would sleep to try to find a FQDN, which it really 477838032Speter really needs. This has been changed to fall through to the 477938032Speter next map type if it can't find a FQDN -- i.e., if the hosts 478038032Speter file doesn't have a FQDN, it will try dns even though the 478138032Speter short name was found in /etc/hosts. This is probably a crock, 478238032Speter but many people have hosts files without FQDNs. Remember: 478338032Speter domain names are your friends. 478438032Speter Log a high-priority message if you can't find your FQDN during startup. 478538032Speter Suggested by Simon Barnes of Schlumberger Limited. 478638032Speter When using Hesiod, initialize it early to improve error reporting. 478738032Speter Patch from Don Lewis of Silicon Systems, Inc. 478838032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 478938032Speter connection timeout in the kernel. Add a new "connect" timeout 479038032Speter to limit this time. Defaults to zero (use whatever the 479138032Speter kernel provides). Based on code contributed by J.R. Oldroyd 479238032Speter of TerraNet. 479338032Speter Under some circumstances, a failed message would not be properly 479438032Speter removed from the queue, causing tons of bogus error messages. 479538032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 479638032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 479738032Speter of WPI. 479838032Speter PORTABILITY FIXES: 479938032Speter On IRIX 5.x, there was an inconsistency in the setting 480038032Speter of sendmail.st location. Change the Makefile to 480138032Speter install it in /var/sendmail.st to match the OSTYPE 480238032Speter file and SGI standards.

Suggested by Per Hedeland of Ericsson. 481638032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 481738032Speter otherwise the F=S causes the From_ line to imply that root is 481838032Speter the sender. Problem pointed out by Claude Scarpelli of 481938032Speter Infobiogen (France). 482038032Speter NEW FILES: 482138032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 482238032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 482338032Speter src/Makefiles/Makefile.UXPDS 482438032Speter 482564562Sgshapiro8.7/8.7 1995/09/16 482638032Speter Fix a problem that could cause sendmail to run out of file 482738032Speter descriptors due to a trashed data structure after a 482838032Speter vfork. Fix from Brian Coan of the Institute for 482938032Speter Global Communications. 483038032Speter Change the VRFY response if you have disabled VRFY -- some 483138032Speter people seemed to think that it was too rude. 483238032Speter Avoid reference to uninitialized file descriptor if HASFLOCK 483338032Speter was not defined. This was used "safely" in the sense 483438032Speter that it only did a stat, but it would have set the 483538032Speter map modification time improperly. Problem pointed out 483638032Speter by Roy Mongiovi of Georgia Tech. 483738032Speter Clean up the Subject: line on warning messages and return 483838032Speter receipts so that they don't say "Returned mail:"; this 483938032Speter can be confusing. 484038032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 484138032Speter useful enough to make it worthwhile printing on "-d". 484238032Speter Avoid logging alias statistics every time you read the alias 484338032Speter file on systems with no database method compiled in. 484438032Speter If you have a name with a trailing dot, and you try looking it 484538032Speter up using gethostbyname without the dot (for /etc/hosts 484638032Speter compatibility), be sure to turn off RES_DEFNAMES and 484738032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 484838032Speter Problem noted by Charles Amos of the University of 484938032Speter Maryland. 485038032Speter Don't do timeouts in collect if you are not running SMTP. 485138032Speter There is nothing that says you can't have a long 485238032Speter running program piped into sendmail (possibly via 485338032Speter /bin/mail, which just execs sendmail). Problem reported 485438032Speter by Don "Truck" Lewis of Silicon Systems. 485538032Speter Try gethostbyname() even if the DNS lookup fails iff option I 485638032Speter is not set. This allows you to have hosts listed in 485738032Speter NIS or /etc/hosts that are not known to DNS. It's normally 485838032Speter a bad idea, but can be useful on firewall machines. This 485938032Speter should really be broken out on a separate flag, I suppose. 486038032Speter Avoid compile warnings against BIND 4.9.3, which uses function 486138032Speter prototypes.

From Kyle Jones of UUNET. 486638032Speter SECURITY: avoid denial-of-service attacks possible by destroying 486738032Speter the alias database file by setting resource limits low. 486838032Speter This involves adding two new compile-time options: 486938032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 487038032Speter available) and HASULIMIT (indicating that ulimit(2) support 487138032Speter is available -- the Release 3 form is used). The former 487238032Speter is assumed on BSD-based systems, the latter on System 487338032Speter V-based systems. Attack noted by Phil Brandenberger of 487438032Speter Swarthmore University. 487538032Speter New syntaxes in test (-bt) mode: 487638032Speter ``.Dmvalue'' will define macro "m" to "value". 487738032Speter ``.Ccvalue'' will add "value" to class "c". 487838032Speter ``=Sruleset'' will dump the contents of the indicated 487938032Speter ruleset. 488038032Speter ``=M'' will display the known mailers. 488138032Speter ``-ddebug-spec'' is equivalent to the command-line 488238032Speter -d debug flag. 488338032Speter ``$m'' will print the value of macro $m. 488438032Speter ``$=c'' will print the contents of class $=c. 488538032Speter ``/mx host'' returns the MX records for ``host''. 488638032Speter ``/parse address'' will parse address, returning the value of 488738032Speter crackaddr (essentially, the comment information) 488838032Speter and the parsed address. 488938032Speter ``/try mailer address'' will rewrite address into the form 489038032Speter it will have when presented to the indicated mailer. 489138032Speter ``/tryflags flags'' will set flags used by parsing. The 489238032Speter flags can be `H' for header or `E' for envelope, 489338032Speter and `S' for sender or `R' for recipient. These 489438032Speter can be combined, so `HR' sets flags for header 489538032Speter recipients. 489638032Speter ``/canon hostname'' will try to canonify hostname and 489738032Speter return the result. 489838032Speter ``/map mapname key'' will look up `key' in the indicated 489938032Speter `mapname' and return the result. 490038032Speter Somewhat better handling of UNIX-domain socket addresses -- it 490138032Speter should show the pathname rather than hex bytes. 490238032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 490338032Speter the header for envelope sender information and uses 490438032Speter CR-LF as message terminators. It was thought to be 490538032Speter obsolete (used only for Arpanet NCP protocols), but it 490638032Speter turns out that the UK ``Grey Book'' protocols require 490738032Speter that functionality. 490838032Speter Fix a fix in previous release -- if gethostname and gethostbyname 490938032Speter return a name without dots, and if an attempt to canonify 491038032Speter that name fails, wait one minute and try again. This can 491138032Speter result in an extra 60 second delay on startup if your system 491238032Speter hostname (as returned by hostname(1)) has no dot and no names 491338032Speter listed in /etc/hosts or your NIS map have a dot. 491438032Speter Check for proper domain name on HELO and EHLO commands per 491538032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 491638032Speter of Michigan Technological University. 491738032Speter Relax chownsafe rules slightly -- old version said that if you 491838032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 491938032Speter if fpathconf returned EINVAL or ENOSYS), assume that 492038032Speter chown is not safe. The new version falls back to whether 492138032Speter you are on a BSD system or not. This is important for 492238032Speter SunOS, which apparently always returns one of those 492338032Speter error codes. This impacts whether you can mail to files 492438032Speter or not. 492538032Speter Syntax errors such as unbalanced parentheses in the configuration 492638032Speter file could be omitted if you had "Oem" prior to the 492738032Speter syntax error in the config file. Change to always print 492838032Speter the error message. It was especially weird because it 492938032Speter would cause a "warning" message to be sent to the Postmaster 493038032Speter for every message sent (but with no transcript). Problem 493138032Speter noted by Gregory Paris of Motorola. 493238032Speter Rewrite collect and putbody to handle full 8-bit data, including 493338032Speter zero bytes. These changes are internally extensive, but 493438032Speter should have minimal impact on external function. 493538032Speter Allow full words for option names -- if the option letter is 493638032Speter (apparently) a space, then take the word following -- e.g., 493738032Speter O MatchGECOS=TRUE 493838032Speter The full list of old and new names is as follows: 493938032Speter 7 SevenBitInput 494038032Speter 8 EightBitMode 494138032Speter A AliasFile 494238032Speter a AliasWait 494338032Speter B BlankSub 494438032Speter b MinFreeBlocks/MaxMessageSize 494538032Speter C CheckpointInterval 494638032Speter c HoldExpensive 494738032Speter D AutoRebuildAliases 494838032Speter d DeliveryMode 494938032Speter E ErrorHeader 495038032Speter e ErrorMode 495138032Speter f SaveFromLine 495238032Speter F TempFileMode 495338032Speter G MatchGECOS 495438032Speter H HelpFile 495538032Speter h MaxHopCount 495638032Speter i IgnoreDots 495738032Speter I ResolverOptions 495838032Speter J ForwardPath 495938032Speter j SendMimeErrors 496038032Speter k ConnectionCacheSize 496138032Speter K ConnectionCacheTimeout 496238032Speter L LogLevel 496338032Speter l UseErrorsTo 496438032Speter m MeToo 496538032Speter n CheckAliases 496638032Speter O DaemonPortOptions 496738032Speter o OldStyleHeaders 496838032Speter P PostmasterCopy 496938032Speter p PrivacyOptions 497038032Speter Q QueueDirectory 497138032Speter q QueueFactor 497238032Speter R DontPruneRoutes 497338032Speter r, T Timeout 497438032Speter S StatusFile 497538032Speter s SuperSafe 497638032Speter t TimeZoneSpec 497738032Speter u DefaultUser 497838032Speter U UserDatabaseSpec 497943730Speter V FallbackMXHost 498038032Speter v Verbose 498138032Speter w TryNullMXList 498238032Speter x QueueLA 498338032Speter X RefuseLA 498438032Speter Y ForkEachJob 498538032Speter y RecipientFactor 498638032Speter z ClassFactor 498738032Speter Z RetryFactor 498838032Speter The old macros that passed information into sendmail have 498938032Speter been changed to options; those correspondences are: 499038032Speter $e SmtpGreetingMessage 499138032Speter $l UnixFromLine 499238032Speter $o OperatorChars 499338032Speter $q (deleted -- not necessary) 499438032Speter To avoid possible problems with an older sendmail, 499538032Speter configuration level 6 is accepted by this version of 499638032Speter sendmail; any config file using the new names should 499738032Speter specify "V6" in the configuration. 499838032Speter Change address parsing to properly note that a phrase before a 499938032Speter colon and a trailing semicolon are essentially the same 500038032Speter as text outside of angle brackets (i.e., sendmail should 500138032Speter treat them as comments). This is to handle the 500238032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 500338032Speter assume that ``group name:'' is a comment on the first 500438032Speter address and the ``;'' is a comment on the last address). 500538032Speter This requires config file support to get right. It does 500638032Speter understand that :: is NOT this syntax, and can be turned 500738032Speter off completely by setting the ColonOkInAddresses option. 500838032Speter Level 6 config files added with new mailer flags: 500938032Speter A Addresses are aliasable. 501038032Speter i Do udb rewriting on envelope as well as header 501138032Speter sender lines. Applies to the from address mailer 501238032Speter flags rather than the recipient mailer flags. 501338032Speter j Do udb rewriting on header recipient addresses. 501438032Speter Applies to the sender mailer flags rather than the 501538032Speter recipient mailer flags. 501638032Speter k Disable check for loops when doing HELO command. 501738032Speter o Always run as the mail recipient, even on local 501838032Speter delivery. 501938032Speter w Check for an /etc/passwd entry for this user. 502038032Speter 5 Pass addresses through ruleset 5. 502138032Speter : Check for :include: on this address. 502238032Speter | Check for |program on this address. 502338032Speter / Check for /file on this address. 502438032Speter @ Look up sender header addresses in the user 502538032Speter database. Applies to the mailer flags for the 502638032Speter mailer corresponding to the envelope sender 502738032Speter address, rather than to recipient mailer flags. 502838032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 502938032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 503038032Speter mailers, and the ColonOkInAddresses option. 503138032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 503238032Speter John Beck of Hewlett-Packard, who generously contributed 503338032Speter their implementation to me, which I then didn't use (see 503438032Speter mime.c for an explanation of why). This adds the 503538032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 503638032Speter to control handling of 8-bit data. These have to cope with 503738032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 503838032Speter 8-bit data that is entered without declaring it as 8-bit 503938032Speter MIME -- technically this is illegal according to the 504038032Speter specs) and labelled 8-bit data (that is, it was declared 504138032Speter as 8BITMIME in the ESMTP session or by using the 504238032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 504338032Speter set then 8-bit data is sent to non-8BITMIME machines 504438032Speter instead of converting to 7 bit (essentially using 504538032Speter just-send-8 semantics). The values for EightBitMode are: 504638032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 504738032Speter any necessary conversion of 8BITMIME to 7BIT 504838032Speter (essentially, the full MIME option). 504938032Speter p pass unlabelled 8-bit input, but convert labelled 505038032Speter 8BITMIME input to 7BIT as required (default). 505138032Speter s strict adherence: reject unlabelled 8-bit input, 505238032Speter convert 8BITMIME to 7BIT as required. The F=8 505338032Speter flag is ignored. 505438032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 505538032Speter the setting of F=8. 505638032Speter Add new internal class 'n', which is the set of MIME Content-Types 505738032Speter which can not be 8 to 7 bit encoded because of other 505838032Speter considerations. Types "multipart/*" and "message/*" are 505938032Speter never directly encoded (although their components can be). 506038032Speter Add new internal class 's', which is the set of subtypes of the 506138032Speter MIME message/* content type that can be treated as though 506238032Speter they are an RFC822 message. It is predefined to have 506338032Speter "rfc822". Suggested By Kari Hurtta. 506438032Speter Add new internal class 'e'. This is the set of MIME 506538032Speter Content-Transfer-Encodings that can be converted to 506638032Speter a seven bit format (Quoted-Printable or Base64). It is 506738032Speter preinitialized to contain "7bit", "8bit", and "binary". 506838032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 506938032Speter short name) to set the default character set to use in the 507038032Speter Content-Type: header when doing encoding of an 8-bit message 507138032Speter which isn't marked as MIME into MIME format. If the C= 507238032Speter parameter is set on the Envelope From address, use that as 507338032Speter the default encoding; else use the DefaultCharSet option. 507438032Speter If neither is set, it defaults to "unknown-8bit" as 507538032Speter suggested by RFC 1428 section 3. 507638032Speter Allow ``U=user:group'' field in mailer definition to set a default 507738032Speter user and group that a mailer will be executed as. This 507838032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 507938032Speter also set, it is the uid/gid that will always be used (that 508038032Speter is, the controlling address is ignored). The values may be 508138032Speter numeric or symbolic; if only a symbolic user is given (no 508238032Speter group) that user's default group in the passwd file is used 508338032Speter as the group. Based on code donated by Chip Rosenthal of 508438032Speter Unicom. 508538032Speter Allow `u' option to also accept user:group as a value, in the same 508638032Speter fashion as the U= mailer option. 508738032Speter Add the symbolic time zone name in the Arpanet format dates (as 508838032Speter a comment). This adds a new compile-time configuration 508938032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 509038032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 509138032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 509238032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 509338032Speter timezone()), or TZ_NONE (don't include the comment). Code 509438032Speter from Chip Rosenthal. 509538032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 509638032Speter For example, 509738032Speter O Timeout.helo = 2m 509838032Speter There are also two new suboptions "queuereturn" and 509938032Speter "queuewarn"; these subsume the old T option. Thus, to 510038032Speter set them both the preferred new syntax is 510138032Speter O Timeout.queuereturn = 5d 510238032Speter O Timeout.queuewarn = 4h 510338032Speter Sort queue by host name instead of by message priority if the 510438032Speter QueueSortOrder option (no short name) is set is set to 510538032Speter ``host''. This makes better use of the connection cache, 510638032Speter but may delay more ``interactive'' messages behind large 510738032Speter backlogs under some circumstances. This is probably a 510838032Speter good option if you have high speed links or don't do lots 510938032Speter of ``batch'' messages, but less good if you are using 511038032Speter something like PPP on a 14.4 modem. Based on code 511138032Speter contributed by Roy Mongiovi of Georgia Tech (my main 511238032Speter contribution was to make it configurable). 511338032Speter Save i-number of df file in qf file to simplify rebuilding of queue 511438032Speter after disastrous disk crash. Suggested by Kyle Jones of 511538032Speter UUNET; closely based on code from KJS DECWRL code written 511638032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 511738032Speter are NOT back compatible with 8.6 -- that is, you can convert 511838032Speter from 8.6 to 8.7, but not the other direction. 511938032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 512038032Speter route-addrs in envelopes; this is because in some cases 512138032Speter they can be sent to the shell, which interprets them as 512238032Speter I/O redirection. 512338032Speter Don't include error file (option E) with return-receipts; this 512438032Speter can be confusing. 512538032Speter Don't send "Warning: cannot send" messages to owner-* or 512638032Speter *-request addresses. Suggested by Christophe Wolfhugel 512738032Speter of the Institut Pasteur, Paris. 512838032Speter Allow -O command line flag to set long form options. 512938032Speter Add "MinQueueAge" option to set the minimum time between attempts 513038032Speter to run the queue. For example, if the queue interval 513138032Speter (-q value) is five minutes, but the minimum queue age 513238032Speter is fifteen minutes, jobs won't be tried more often than 513338032Speter once every fifteen minutes. This can be used to give 513438032Speter you more responsiveness if your delivery mode is set to 513538032Speter queue-only. 513638032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 513738032Speter :include: and .forward files. 513838032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 513938032Speter key field name, the value field name, and the field 514038032Speter delimiter. The field delimiter can be a single character 514138032Speter or the sequence "\t" or "\n" for tab or newline. 514238032Speter These are for use by NIS+ and similar access methods. 514338032Speter Change maps to always strip quotes before lookups; the -q flag 514443730Speter turns off this behavior. Suggested by Motonori Nakamura. 514538032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 514638032Speter key and value field names respectively. Code donated by 514738032Speter Sun Microsystems. 514838032Speter Add "hesiod" map class. The "file name" is used as the 514938032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 515038032Speter first value found for the match. Code donated by Scott 515138032Speter Hutton of Indiana University. 515238032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 515338032Speter specify the name of the property that is searched as the 515438032Speter key and a -v flag to specify the name of the property that 515538032Speter is returned as the value (defaults to "members"). The 515638032Speter default map is "/aliases". Some code based on code 515738032Speter contributed by Robert La Ferla of Hot Software. 515838032Speter Add "text" map class. This does slow, linear searches through 515938032Speter text files. The -z flag specifies a column delimiter 516038032Speter (defaults to any sequence of white space), the -k flag 516138032Speter sets the key column number, and the -v flag sets the 516238032Speter value column number. Lines beginning with `#' are treated 516338032Speter as comments. 516438032Speter Add "program" map class to execute arbitrary programs. The search 516538032Speter key is presented as the last argument; the output is one 516638032Speter line read from the programs standard output. Exit statuses 516738032Speter are from sysexits.h. 516838032Speter Add "sequence" map class -- searches maps in sequence until it 516938032Speter finds a match. For example, the declarations: 517038032Speter Kmap1 ... 517138032Speter Kmap2 ... 517238032Speter Kmapseq sequence map1 map2 517338032Speter defines a map "mapseq" that first searches map1; if the 517438032Speter value is found it is returned immediately, otherwise 517538032Speter map2 is searched and the value returned. 517638032Speter Add "switch" map class. This is much like "sequence" except that 517738032Speter the ordering is fetched from an external file, usually 517838032Speter the system service switch. The parameter is the name of 517938032Speter the service to switch on, and the maps that it will use 518038032Speter are the name of the switch map followed by ".service_type". 518138032Speter For example, if the declaration of the map is 518238032Speter Ksample switch hosts 518338032Speter and the system service switch specifies that hosts are 518438032Speter looked up using dns and nis in that order, then this is 518538032Speter equivalent to 518638032Speter Ksample sequence sample.dns sample.nis 518738032Speter The subordinate maps (sample.*) must already be defined. 518838032Speter Add "user" map class -- looks up users using getpwnam. Takes a 518938032Speter "-v field" flag on the definition that tells what passwd 519038032Speter entry to return -- legal values are name, passwd, uid, gid, 519138032Speter gecos, dir, and shell. Generally expected to be used with 519238032Speter the -m (matchonly) flag. 519338032Speter Add "bestmx" map class -- returns the best MX value for the host 519438032Speter listed as the value. If there are several "best" MX records 519538032Speter for this host, one will be chosen at random. 519638032Speter Add "userdb" map class -- looks up entries in the user database. 519738032Speter The "file name" is actually the tag that will be used, 519838032Speter typically "mailname". If there are multiple entries 519938032Speter matching the name, the one chosen is undefined. 520038032Speter Add multiple queue timeouts (both return and warning). These are 520138032Speter set by the Precedence: or Priority: header fields to one of 520238032Speter three values. If a Priority: is set and has value "normal", 520364562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 520438032Speter used. If no priority is set, the Precedence: is consulted; 520538032Speter if negative, non-urgent timeouts are used; if greater than 520638032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 520738032Speter are used. The timeouts are set by setting the six timeouts 520838032Speter queue{warn,return}.{urgent,normal,non-urgent}. 520938032Speter Fix problem when a mail address is resolved to a $#error mailer 521038032Speter with a temporary failure indication; it works in SMTP, 521138032Speter but when delivering locally the mail is silently discarded. 521238032Speter This patch, from Kyle Jones of UUNET, bounces it instead 521338032Speter of queueing it (queueing is very hard). 521438032Speter When using /etc/hosts or NIS-style lookups, don't assume that 521538032Speter the first name in the list is the best one -- instead, 521638032Speter search for the first one with a dot. For example, if 521738032Speter an /etc/hosts entry reads 521838032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 521938032Speter this change will use the second name as the canonical 522038032Speter machine name instead of the initial, unqualified name. 522138032Speter Change dequote map to replace spaces in quoted text with a value 522238032Speter indicated by the -s flag on the dequote map definition. 522338032Speter For example, ``Mdequote dequote -s_'' will change 522438032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 522538032Speter quoted (because of the space character). Suggested by Dan 522638032Speter Oscarsson for use in X.400 addresses. 522738032Speter Implement long macro names as ${name}; long class names can 522838032Speter be similarly referenced as $={name} and $~{name}. 522938032Speter Definitions are (e.g.) ``D{name}value''. Names that have 523038032Speter a leading lower case letter or punctuation characters are 523138032Speter reserved for internal use by sendmail; i.e., config files 523238032Speter should use names that begin with a capital letter. Based 523338032Speter on code contributed by Dan Oscarsson. 523438032Speter Fix core dump if getgrgid returns a null group list (as opposed 523538032Speter to an empty group list, that is, a pointer to a list 523638032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 523738032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 523838032Speter failed, it called syserr which called newstr which called 523938032Speter xalloc.... The newstr is now avoided for "panic" messages. 524038032Speter Reported by Stuart Kemp of James Cook University. 524138032Speter Improve connection cache timeouts; previously, they were not even 524238032Speter checked if you were delivering to anything other than an 524338032Speter IPC-connected host, so a series of (say) local mail 524438032Speter deliveries could cause cached connections to be open 524538032Speter much longer than the specified timeout. 524638032Speter If an incoming message exceeds the maximum message size, stop 524738032Speter writing the incoming bytes to the queue data file, since 524838032Speter this can fill your mqueue partition -- this is a possible 524938032Speter denial-of-service attack. 525038032Speter Don't reject all numeric local user names unless HESIOD is 525138032Speter defined. It turns out that Posix allows all-numeric 525238032Speter user names. Fix from Tony Sanders of BSDI. 525338032Speter Add service switch support. If the local OS has a service 525438032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 525538032Speter on DEC systems) that will be used; otherwise, it falls back 525638032Speter to using a local mechanism based on the ServiceSwitchFile 525738032Speter option (default: /etc/service.switch). For example, if the 525838032Speter service switch lists "files" and "nis" for the aliases 525938032Speter service, that will be the default lookup order. the "files" 526038032Speter ("local" on DEC) service type expands to any alias files 526138032Speter you listed in the configuration file, even if they aren't 526238032Speter actually file lookups. 526338032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 526438032Speter variable which tells whether or not DNS should be considered 526538032Speter canonical. This is now determined based on whether or not 526638032Speter "dns" is in the service list for "hosts". 526738032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 526838032Speter Status Notifications). DSN notifications override 526938032Speter Return-Receipt-To: headers, which are bogus anyhow -- 527038032Speter support for them has been removed. 527138032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 527238032Speter definitions to define the types used in DSN returns for 527338032Speter MTA names, addresses, and diagnostics respectively. 527438032Speter Extend heuristic to force running in ESMTP mode to look for the 527538032Speter five-character string "ESMTP" anywhere in the 220 greeting 527638032Speter message (not just the second line). This is to provide 527738032Speter better compatibility with other ESMTP servers. 527838032Speter Print sequence number of job when running the queue so you can 527938032Speter easily see how much progress you have made. Suggested 528038032Speter by Peter Wemm of DIALix. 528138032Speter Map newlines to spaces in logged message-ids; some versions of 528238032Speter syslog truncate the rest of the line after newlines. 528338032Speter Suggested by Fletcher Mattox of U. Texas. 528438032Speter Move up forking for job runs so that if a message is split into 528538032Speter multiple envelopes you don't get "fork storms" -- this 528638032Speter also improves the connection cache utilization. 528738032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 528838032Speter the purposes of refusing to send error returns. Suggested 528938032Speter by Motonori Nakamura of Ritsumeikan University. 529038032Speter Relax rules on when a file can be written when referenced from 529138032Speter the aliases file: use the default uid/gid instead of the 529238032Speter real uid/gid. This allows you to create a file owned by 529338032Speter and writable only by the default uid/gid that will work 529438032Speter all the time (without having the setuid bit set). Change 529538032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 529638032Speter Microsystems. 529738032Speter Add "DialDelay" option (no short name) to provide an "extra" 529838032Speter delay for dial on demand systems. If this is non-zero 529938032Speter and a connect fails, sendmail will wait this long and 530038032Speter then try again. If it takes longer than the kernel 530138032Speter timeout interval to establish the connection, this 530238032Speter option can give the network software time to establish 530338032Speter the link. The default units are seconds. 530438032Speter Move logging of sender information to be as early as possible; 530538032Speter previously, it could be delayed a while for SMTP mail 530638032Speter sent to aliases. Suggested by Brad Knowles of the 530738032Speter Defense Information Systems Agency. 530838032Speter Call res_init() before setting RES_DEBUG; this is required by 530938032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 531038032Speter the National Computer Security Center. 531138032Speter Add xdelay= field in logs -- this is a transaction delay, telling 531238032Speter you how long it took to deliver to this address on the 531338032Speter last try. It is intended to be used for sorting mailing 531438032Speter lists to favor "quick" addresses. Provided for use by 531538032Speter the mailprio scripts (see below). 531638032Speter If a map cannot be opened, and that map is non-optional, and 531738032Speter an address requires that map for resolution, queue the 531838032Speter map instead of bouncing it. This involves creating a 531938032Speter pseudo-class of maps called "bogus-map" -- if a required 532038032Speter map cannot be opened, the class is changed to bogus-map; 532138032Speter all queries against bogus-map return "tempfail". The 532238032Speter bogus-map class is not directly accessible. A sample 532338032Speter implementation was donated by Jem Taylor of Glasgow 532438032Speter University Computing Service. 532538032Speter Fix a possible core dump when mailing to a program that talks 532638032Speter SMTP on its standard input. Fix from Keith Moore of 532738032Speter the University of Kentucky. 532838032Speter Make it possible to resolve filenames to $#local $: @ /filename; 532938032Speter previously, the "@" would cause it to not be recognized 533038032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 533138032Speter Accept a -1 signal to re-exec the daemon. This only works if 533238032Speter argv[0] is a full path to sendmail. 533338032Speter Fix bug in "addr=..." field in O option on little-endian machines 533438032Speter -- the network number wasn't being converted to network 533538032Speter byte order. Patch from Kurt Lidl of Pix Technologies 533638032Speter Corporation. 533738032Speter Pre-initialize the resolver early on; this is to avoid a bug with 533838032Speter BIND 4.9.3 that can cause the _res.retry field to get 533938032Speter reset to zero, causing all name server lookups to time 534038032Speter out. Fix from Matt Day of Artisoft. 534138032Speter Restore T line (trusted users) in config file -- but instead of 534238032Speter locking out the -f flag, they just tell whether or not 534338032Speter an X-Authentication-Warning: will be added. This really 534438032Speter just creates new entries in class 't', so "Ft/file/name" 534538032Speter can be used to read trusted user names from a file. 534638032Speter Trusted users are also allowed to execute programs even 534738032Speter if they have a shell that isn't in /etc/shells. 534838032Speter Improve NEWDB alias file rebuilding so it will create them 534938032Speter properly if they do not already exist. This had been 535038032Speter a MAYBENEXTRELEASE feature in 8.6.9. 535138032Speter Check for @:@ entry in NIS maps before starting up to avoid 535238032Speter (but not prevent, sigh) race conditions. This ought to 535338032Speter be handled properly in ypserv, but isn't. Suggested by 535438032Speter Michael Beirne of Motorola. 535538032Speter Refuse connections if there isn't enough space on the filesystem 535638032Speter holding the queue. Contributed by Robert Dana of Wolf 535738032Speter Communications. 535838032Speter Skip checking for directory permissions in the path to a file 535938032Speter when checking for file permissions iff setreuid() 536038032Speter succeeded -- it is unnecessary in that case. This avoids 536138032Speter significant performance problems when looking for .forward 536238032Speter files. Based on a suggestion by Win Bent of USC. 536338032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 536438032Speter arbitrary ruleset number assigned or "Sname = integer" 536538032Speter to assign a specific ruleset number. Reference is 536638032Speter $>name_or_number. Names can be composed of alphas, digits, 536738032Speter underscore, or hyphen (first character must be non-numeric). 536838032Speter Allow -o flag on AliasFile lines to make the alias file optional. 536938032Speter From Bryan Costales of ICSI. 537038032Speter Add NoRecipientAction option to handle the case where there is 537138032Speter no legal recipient header in the message. It can take 537238032Speter on values: 537338032Speter None Leave the message as is. The 537438032Speter message will be passed on even 537538032Speter though it is in technically 537638032Speter illegal syntax. 537738032Speter Add-To Add a To: header with any 537838032Speter recipients that it can find from 537938032Speter the envelope. This risks exposing 538038032Speter Bcc: recipients. 538138032Speter Add-Apparently-To Add an Apparently-To: header. This 538238032Speter has almost no redeeming social value, 538338032Speter and is provided only for back 538438032Speter compatibility. 538538032Speter Add-To-Undisclosed Add a header reading 538638032Speter To: undisclosed-recipients:; 538738032Speter which will have the effect of 538838032Speter making the message legal without 538938032Speter exposing Bcc: recipients. 539038032Speter Add-Bcc To add an empty Bcc: header. 539138032Speter There is a chance that mailers down 539238032Speter the line will delete this header, 539338032Speter which could cause exposure of Bcc: 539438032Speter recipients. 539538032Speter The default is NoRecipientAction=None. 539638032Speter Truncate (rather than delete) Bcc: lines in the header. This 539738032Speter should prevent later sendmails (at least, those that don't 539838032Speter themselves delete Bcc:) from considering this message to 539938032Speter be non-conforming -- although it does imply that non-blind 540038032Speter recipients can see that a Bcc: was sent, albeit not to whom. 540138032Speter Add SafeFileEnvironment option. If declared, files named as delivery 540238032Speter targets must be regular files in addition to the regular 540338032Speter checks. Also, if the option is non-null then it is used as 540438032Speter the name of a directory that is used as a chroot(2) 540538032Speter environment for the delivery; the file names listed in an 540638032Speter alias or forward should include the name of this root. 540738032Speter For example, if you run with 540838032Speter O SafeFileEnvironment=/arch 540938032Speter then aliases should reference "/arch/rest/of/path". If a 541038032Speter value is given, sendmail also won't try to save to 541138032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 541238032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 541338032Speter Support -A flag for alias files; this will comma concatenate like 541438032Speter entries. For example, given the aliases: 541538032Speter list: member1 541638032Speter list: member2 541738032Speter and an alias file declared as: 541838032Speter OAhash:-A /etc/aliases 541938032Speter the final alias inserted will be "list: member1,member2"; 542038032Speter without -A you will get an error on the second and subsequent 542138032Speter alias for "list". Contributed by Bryan Costales of ICSI. 542238032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 542338032Speter Fix a problem that could cause very long addresses to core dump in 542438032Speter some special circumstances. Problem pointed out by Allan 542538032Speter Johannesen. 542638032Speter (Internal change.) Change interface to expand() (macro expansion) 542738032Speter to be simpler and more consistent. 542838032Speter Delete check for funny qf file names. This didn't really give 542938032Speter any extra security and caused some people some problems. 543038032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 543138032Speter at compile time.) Suggested by Kyle Jones of UUNET. 543238032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 543338032Speter merge with DSN code; this is simpler and more consistent. 543438032Speter This may affect some people who have written their own 543538032Speter checkcompat() routine. 543638032Speter (Internal change.) Eliminate `D' line in qf file. The df file 543738032Speter is now assumed to be the same name as the qf file (with 543838032Speter the `q' changed to a `d', of course). 543938032Speter Avoid forking for delivery if all recipient mailers are marked as 544038032Speter "expensive" -- this can be a major cost on some systems. 544138032Speter Essentially, this forces sendmail into "queue only" mode 544238032Speter if all it is going to do is queue anyway. 544338032Speter Avoid sending a null message in some rather unusual circumstances 544438032Speter (specifically, the RCPT command returns a temporary 544538032Speter failure but the connection is lost before the DATA 544638032Speter command). Fix from Scott Hammond of Secure Computing 544738032Speter Corporation. 544838032Speter Change makesendmail to use a somewhat more rational naming scheme: 544938032Speter Makefiles and obj directories are named $os.$rel.$arch, 545038032Speter where $os is the operating system (e.g., SunOS), $rel is 545138032Speter the release number (e.g., 5.3), and $arch is the machine 545238032Speter architecture (e.g., sun4). Any of these can be omitted, 545338032Speter and anything after the first dot in a release number can 545438032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 545538032Speter version used $os.$arch.$rel and was rather less general. 545638032Speter Change makesendmail to do a "make depend" in the target directory 545738032Speter when it is being created. This involves adding an empty 545838032Speter "depend:" entry in most Makefiles. 545938032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 546038032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 546138032Speter of the Finnish Meteorological Institute. 546238032Speter Fix problem that could cause multiple responses to DATA command 546338032Speter on header syntax errors (e.g., lines beginning with colons). 546438032Speter Problem noted by Jens Thomassen of the University of Oslo. 546538032Speter Don't let null bytes in headers cause truncation of the rest of 546638032Speter the header. 546738032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 546838032Speter Increase timeouts on message data puts to allow time for receivers 546938032Speter to canonify addresses in headers on the fly. This is still 547038032Speter a rather ugly heuristic. From Motonori Nakamura. 547138032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 547238032Speter records are not used when canonifying names, and when MX 547338032Speter lookups are done for addressing they must be fully 547438032Speter qualified. This is useful if you have a wildcard MX record, 547538032Speter although it may cause other problems. In general, don't use 547638032Speter wildcard MX records. Patch from Motonori Nakamura. 547738032Speter Eliminate default two-line SMTP greeting message. Instead of 547838032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 547938032Speter is added between the first and second word of the first 548038032Speter line of the greeting message (i.e., immediately after the 548138032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 548238032Speter compile flag. Old sendmails won't see the ESMTP, but that's 548338032Speter acceptable because SIZE was the only useful extension that 548438032Speter old sendmails understand. 548538032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 548638032Speter invoked state dumps. From Masaharu Onishi. 548738032Speter Allow on-line comments in .forward and :include: files; they are 548838032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 548938032Speter is a space or a tab. This is intended for native 549038032Speter representation of non-ASCII sets such as Japanese, where 549138032Speter existing encodings would be unreadable or would lose 549238032Speter data -- for example, 549338032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 549438032Speter (romanized/less information) 549538032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 549638032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 549738032Speter (with MIME encoding, not human readable) 549838032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 549938032Speter (native encoding with ISO-2022-JP) 550038032Speter The last form is human readable in the Japanese environment. 550138032Speter Based on a fix from (surprise!) Motonori Nakamura. 550238032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 550338032Speter messages to that host; these are most frequently associated 550438032Speter with addresses rather than the host, with the exception of 550538032Speter 421 (service shutting down). The effect was to cause queues 550638032Speter to sometimes take an excessive time to flush. Reported by 550738032Speter Robert Sargent of Southern Geographics Technologies and 550838032Speter Eric Prestemon of American University. 550938032Speter Add Nice=N mailer option to set the niceness at which a mailer will 551038032Speter run. This is actually a relative niceness (that is, an 551138032Speter increment on the background value). 551238032Speter Log queue runs that are skipped due to high loads. They are logged 551338032Speter at LOG_INFO priority iff the log level is > 8. Contributed 551438032Speter by Bruce Nagel of Data General. 551538032Speter Allow the error mailer to accept a DSN-style error status code 551638032Speter instead of an sysexits status code in the host part. 551738032Speter Anything with a dot will be interpreted as a DSN-style code. 551838032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 551938032Speter to encode characters that might be munged by an EBCDIC system 552038032Speter in addition to the set required by RFC 1521. The additional 552138032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 552238032Speter (Think of "IBM 360" as the mnemonic for this flag.) 552338032Speter Change check for mailing to files to look for a pathname of [FILE] 552438032Speter rather than looking for the mailer named *file*. The mapping 552538032Speter of leading slashes still goes to the *file* mailer. This 552638032Speter allows you to implement the *file* mailer as a separate 552738032Speter program, for example, to insert a Content-Length: header 552838032Speter or do special security policy. However, note that the usual 552938032Speter initial checking for the file permissions is still done, and 553038032Speter the program in question needs to be very careful about how 553138032Speter it does the file write to avoid security problems. 553238032Speter Be able to read ~root/.forward even if the path isn't accessible to 553338032Speter regular users. This is disrecommended because sendmail 553438032Speter sometimes does not run as root (e.g., when an unsafe option 553538032Speter is specified on the command line), but should otherwise be 553638032Speter safe because .forward files must be owned by the user for 553738032Speter whom mail is being forwarded, and cannot be a symbolic link. 553838032Speter Suggested by Forrest Aldrich of Wang Laboratories. 553938032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 554038032Speter file. This is used for canonifying hostnames when the 554138032Speter service type is "files". 554238032Speter Implement programs on F (read class from file) line. The syntax is 554338032Speter Fc|/path/to/program to read the output from the program 554438032Speter into class "c". 554538032Speter Probe the network interfaces to find alternate names for this 554638032Speter host. Requires the SIOCGIFCONF ioctl call. Code 554738032Speter contributed by SunSoft. 554838032Speter Add "E" configuration line to set or propagate environment 554938032Speter variables into children. "E<envar>" will propagate 555038032Speter the named variable from the environment when sendmail 555138032Speter was invoked into any children it calls; "E<envar>=<value>" 555238032Speter sets the named variable to the indicated value. Any 555338032Speter variables not explicitly named will not be in the child 555438032Speter environment. However, sendmail still forces an 555538032Speter "AGENT=sendmail" environment variable, in part to enforce 555638032Speter at least one environment variable, since many programs and 555738032Speter libraries die horribly if this is not guaranteed. 555838032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 555938032Speter alias databases -- new algorithm looks for the substring 556038032Speter "/yp/" in the file name. This is more portable and involves 556138032Speter less overhead. Suggested by Motonori Nakamura. 556238032Speter Dynamically allocate the queue work list so that you don't lose 556338032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 556438032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 556538032Speter should not need to be changed) and the MaxQueueRunSize option, 556638032Speter which is the absolute maximum number of jobs that will ever 556738032Speter be handled in a single queue run. Based on code contributed 556838032Speter by Brian Coan of the Institute for Global Communications. 556938032Speter Log message when a message is dropped because it exceeds the maximum 557038032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 557138032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 557238032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 557338032Speter of Mark G. Thomas Consulting. 557438032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 557538032Speter OS-dependent defines). The old semantic of -d0.1 to not 557638032Speter run the daemon in background has been moved to -d99.100, 557738032Speter and the old 52.5 flag (to avoid disconnect() from closing 557838032Speter all output files) has been moved to 52.100. This makes 557938032Speter things more consistent (flags below .100 don't change 558038032Speter semantics) and separates out the backgrounding so that 558138032Speter it doesn't happen automatically on other unrelated debugging 558238032Speter flags. 558338032Speter If -t is used but no addresses are found in the header, give an 558438032Speter error message rather than just doing nothing. Fix from 558538032Speter Motonori Nakamura. 558638032Speter On systems (like SunOS) where the effective gid is not necessarily 558738032Speter included in the group list returned by getgroups(), the 558838032Speter `restrictmailq' option could sometimes cause an authorized 558938032Speter user to not be able to use `mailq'. Fix from Charles Hannum 559038032Speter of MIT. 559138032Speter Allow symbolic service names for [IPC] mailers. Suggested by 559238032Speter Gerry Magennis of Logica International. 559338032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 559438032Speter when running DNS. For example, if the name FTP.Foo.ORG is 559538032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 559638032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 559738032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 559838032Speter This is technically illegal under RFC 822 and 1123, but the 559938032Speter IETF is moving toward legalizing it. Note that turning on 560038032Speter this option is not sufficient to guarantee that a downstream 560138032Speter neighbor won't rewrite the address for you. 560238032Speter Add "-m" flag to makesendmail script -- this tells you what object 560338032Speter directory and Makefile it will use, but doesn't actually do 560438032Speter the make. 560538032Speter Do some additional checking on the contents of the qf file to try 560638032Speter to detect attacks against the qf file. In particular, 560738032Speter abort on any line beginning "From ", and add an "end of 560838032Speter file" line -- any data after that line is prohibited. 560938032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 561038032Speter choices. This can be overridden in the Makefile by using 561138032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 561238032Speter (to the extent that we know it) or by defining 561338032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 561438032Speter sendmail 8 to have more consistent installation instructions. 561538032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 561638032Speter of Sun Microsystems. 561738032Speter Improved symbol table hash function from Eric Wassenaar. This one 561838032Speter is at least 50% faster. 561938032Speter Fix problem that didn't notice that timeout on file open was a 562038032Speter transient error. Fix from Larry Parmelee of Cornell 562138032Speter University. 562238032Speter Allow comments (lines beginning with a `#') in files read for 562338032Speter classes. Suggested by Motonori Nakamura. 562438032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 562538032Speter of dropping out entirely. This makes testing some of the 562638032Speter name server lookups easier to deal with when there are 562738032Speter hung servers. From Motonori Nakamura. 562838032Speter Add new ${opMode} macro that is set to the current operation mode 562938032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 563038032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 563138032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 563238032Speter Kind of like queue-only mode (Odq) except it tries to avoid 563338032Speter any external service requests; for dial-on-demand hosts that 563438032Speter want to minimize DNS lookups when mail is being queued. For 563538032Speter this to work you will also have to make sure that gethostbyname 563638032Speter of your local host name does not do a DNS lookup. 563738032Speter Improved handling of "out of space" conditions from John Myers of 563838032Speter Carnegie Mellon. 563938032Speter Improved security for mailing to files on systems that have fchmod(2) 564038032Speter support. 564138032Speter Improve "cannot send message for N days" message -- now says "could 564238032Speter not send for past N days". Suggested by Tom Moore of AT&T 564338032Speter Global Information Solutions. 564438032Speter Less misleading Subject: line on messages sent to postmaster only. 564538032Speter From Motonori Nakamura. 564638032Speter Avoid duplicate error messages on bad command line flags.

Problem reported by David 565438032Speter James of British Telecom. 565538032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 565638032Speter from Alexander Dupuy of System Management ARTS. 565738032Speter Delete duplicates in MX lists -- believe it or not, there are sites 565838032Speter that list the same host twice in an MX list. This deletion 565938032Speter only works on adjacent preferences, so an MX list that 566038032Speter had A=5, B=10, A=15 would leave both As, but one that had 566138032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 566238032Speter just in case there is something weird I haven't thought of. 566338032Speter Suggested by Barry Shein of Software Tool & Die. 566438032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 575938032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 576038032Speter University of Brno (Czech Republic). 576138032Speter KSR OS 1.2.2 support from Todd Miller of the University 576238032Speter of Colorado. 576338032Speter UX4800 support from Kazuhisa Shimizu of NEC. 576438032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 576538032Speter in type ``btree'' maps. The semantics of this are undefined 576638032Speter for regular maps, but it can be useful for the user database. 576738032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 576838032Speter lookups while the rebuild is going on. There is a race 576938032Speter condition between the open(... O_TRUNC ...) and the lock 577038032Speter on the file, but it should be quite small. 577138032Speter SMRSH: sendmail restricted shell added to the release. This can 577238032Speter be used as an alternative to /bin/sh for the "prog" mailer, 577338032Speter giving the local administrator more control over what 577438032Speter programs can be run from sendmail. 577538032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 577638032Speter part of the release proper, and isn't fully supported; in 577738032Speter particular, it does not run on System V based systems and 577838032Speter never will. 577938032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 578038032Speter to allow rmail to compile on systems that don't have 578138032Speter function prototypes and systems that don't have snprintf. 578238032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 578338032Speter lists by transaction delay times so that addresses that 578438032Speter respond quickly get sent first. This is to prevent very 578538032Speter sluggish servers from delaying other peoples' mail. 578638032Speter Contributed by Tony Sanders of BSDI. 578738032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 578838032Speter of BSDI. This has a lot of comments to help people out. 578938032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 579038032Speter put this on the m4 command line. On GNU m4 (which 579138032Speter supports the __file__ primitive) you can run m4 in an 579238032Speter arbitrary directory -- use either: 579338032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 579438032Speter or 579538032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 579638032Speter On other versions of m4 that don't support __file__, you 579738032Speter can use: 579838032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 579938032Speter (Note the trailing slash on the _CF_DIR_ definition.) 580038032Speter Old versions of m4 will default to _CF_DIR_=.. for back 580138032Speter compatibility. 580238032Speter CONFIG: fix mail from <> so it will properly convert to 580338032Speter MAILER-DAEMON on local addresses. 580438032Speter CONFIG: fix code that was supposed to catch colons in host 580538032Speter names. Problem noted by John Gardiner Myers of CMU. 580638032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 580738032Speter From Paul Riddle of the University of Maryland, Baltimore 580838032Speter County. 580938032Speter CONFIG: Catch and reject "." as a host address. 581038032Speter CONFIG: Generalize domaintable to look up all domains, not 581138032Speter just unqualified ones. 581238032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 581338032Speter was never used and didn't work anyway. 581438032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 581538032Speter and d on all mailers in the UUCP class. 581638032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 581738032Speter look for an alias for "user+detail", then for "user+*", and 581838032Speter finally for "user". This is intended for forwarding mail 581938032Speter for system aliases such as root and postmaster to a 582038032Speter centralized hub. 582138032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 582238032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 582338032Speter The F=8 flag is also set on the "relay" mailer, since 582438032Speter this is expected to be another sendmail. 582538032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 582638032Speter the name of the UUCP_RELAY -- in some cases, this is the 582738032Speter wrong value (e.g., when we have local UUCP connections), 582838032Speter and this can create unreplyable addresses. From Chip 582938032Speter Rosenthal of Unicom. 583038032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 583164562Sgshapiro Received: header inserted into all messages. Suggested by 583238032Speter Gary Mills of the University of Manitoba. 583338032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 583443730Speter to get the old behavior. I did this upon observing 583538032Speter that almost everyone needed this feature, and that the 583638032Speter concept I was trying to make happen didn't work with 583738032Speter some user agents anyway. FEATURE(notsticky) still works, 583838032Speter but it is a no-op. 583938032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 584038032Speter names are sent, rather than immediately diagnosing them 584138032Speter as User Unknown. 584238032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 584338032Speter and RELAY_MAILER_ARGS to set the arguments for the 584438032Speter indicated mailers. All default to "IPC $h". Patch from 584538032Speter Larry Parmelee of Cornell University. 584638032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 584738032Speter on the client side" and F=P to get an appropriate 584838032Speter return-path. From Kimmo Suominen. 584938032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 585038032Speter as the local mailer. For addresses of the form "user+detail" 585138032Speter the "detail" part is passed to procmail via the -a flag. 585238032Speter Contributed by Kimmo Suominen. 585338032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 585438032Speter use from mailertables. This lets you execute arbitrary 585538032Speter procmail scripts. Contributed by Kimmo Suominen. 585638032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 585738032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 585838032Speter Paul Southworth of CICNet Systems Support. 585938032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 586038032Speter This causes the null return path to be rewritten as 586138032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 586238032Speter From Michael Hohmuth of Technische Universitat Dresden. 586338032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 586438032Speter list us as the best possible MX record to be treated as 586538032Speter though they were local (essentially, assume that they 586638032Speter are included in $=w). This can cause additional DNS 586738032Speter traffic, but is easier to administer if this fits your 586838032Speter local model. It does not work reliably if there are 586938032Speter multiple hosts that share the best MX preference. 587038032Speter Code contributed by John Oleynick of Rutgers. 587138032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 587238032Speter SHell) instead of /bin/sh as the program used for delivery 587338032Speter to programs. If an argument is included, it is used as 587438032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 587538032Speter assumed. 587638032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 587738032Speter size of messages to the local and procmail mailers 587838032Speter respectively. Contributed by Brad Knowles of the Defense 587938032Speter Information Systems Agency. 588038032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 588138032Speter (just like text outside of angle brackets) in order to 588238032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 588338032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 588438032Speter any real systems any more) and tweak the DOMAIN macro 588538032Speter so that it is less likely that users will accidentally use 588638032Speter the Berkeley defaults. Also, create some generic files 588738032Speter that really can be used in the real world. 588838032Speter CONFIG: Add new configuration macros to set character sets for 588938032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 589038032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 589138032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 589238032Speter The old name will still be accepted for a while at least. 589338032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 589438032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 589538032Speter As with all relays, it can be ``mailer:hostname''. Suggested 589638032Speter by Scott Hutton. 589738032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 589838032Speter by Barb Dijker of Labyrinth Computer Services. 589938032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 590038032Speter performance for large alias files, and this confused many 590138032Speter people. 590238032Speter CONFIG: Add confCF_VERSION to append local information to the 590338032Speter configuration version number displayed during SMTP startup. 590438032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 590538032Speter would only work when locally addressed. Fix from 590638032Speter Edvard Tuinder of Cistron Internet Services. 590738032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 590843730Speter "n" (CheckAliases) is set when rebuilding alias database. 590938032Speter Based on code contributed by Claude Marinier. 591038032Speter CONFIG: Allow mailertable to have values of the form 591138032Speter ``error:code message''. The ``code'' is a status code 591238032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 591338032Speter Contributed by David James <dwj@agw.bt.co.uk>. 591438032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 591538032Speter sender domains that will be replaced with the masquerade name. 591638032Speter These domains will not be treated as local, but if mail passes 591738032Speter through with sender addresses in those domains they will be 591838032Speter replaced by the masquerade name. These can also be specified 591938032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 592038032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 592138032Speter as well as the header. Substantial improvements to this 592238032Speter code were contributed by Per Hedeland. 592338032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 592438032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 592538032Speter by Kimmo Suominen. 592638032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 592738032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 592838032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 592938032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 593038032Speter UUCP addressing.

This caused UnixWare 607338032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 607438032Speter Novell Labs Europe. 607538032Speter Fix problem with static linking of local getopt routine when 607638032Speter using GNU's ld command. Fix from John Kennedy of 607738032Speter Cal State Chico. 607838032Speter It was possible to turn off privacy flags. Problem noted by 607938032Speter *Hobbit*. 608038032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 608138032Speter and Liudvikas Bukys. 608238032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 608338032Speter from Spider Boardman. 608438032Speter CONFIG: No changes (version number only, to keep it in sync 608538032Speter with the binaries). 608638032Speter 608764562Sgshapiro8.6.10/8.6.10 1995/02/10 608838032Speter SECURITY: Diagnose bogus values to some command line flags that 608938032Speter could allow trash to get into headers and qf files. 609038032Speter Validate the name of the user returned by the IDENT protocol. 609138032Speter Some systems that really dislike IDENT send intentionally 609238032Speter bogus information. Problem pointed out by Michael Bushnell 609338032Speter of the Free Software Foundation. Has some security 609438032Speter implications. 609538032Speter Fix a problem causing error messages about DNS problems when 609638032Speter the host name contained a percent sign to act oddly 609738032Speter because it was passed as a printf-style format string. 609838032Speter In some cases this could cause core dumps. 609938032Speter Avoid possible buffer overrun in returntosender() if error 610038032Speter message is quite long. From Fletcher Mattox of the 610138032Speter University of Texas. 610238032Speter Fix a problem that would silently drop "too many hops" error 610338032Speter messages if and only if you were sending to an alias. 610438032Speter From Jon Giltner of the University of Colorado and 610538032Speter Dan Harton of Oak Ridge National Laboratory. 610638032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 610738032Speter set and e->e_message was null. Fix from Bruce Nagel of 610838032Speter Data General. 610938032Speter Fix problem that can still cause df files to be left around 611038032Speter after "hop count exceeded" messages. Fix from Andrew 611138032Speter Chang and Shau-Ping Lo of SunSoft. 611238032Speter Fix a problem that can cause buffer overflows on very long 611338032Speter user names (as might occur if you piped to a program 611438032Speter with a lot of arguments). 611538032Speter Avoid returning an error and re-queueing if the host signature 611638032Speter is null; this can occur on addresses like ``user@.''. 611738032Speter Problem noted by Wesley Craig and the University of 611838032Speter Michigan. 611938032Speter Avoid possible calls to malloc(0) if MCI caching is turned 612038032Speter off. Bug fix from Pierre David of the Laboratoire 612138032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 612238032Speter Universite de Versailles - St Quentin, and Jacky 612338032Speter Thibault. 612438032Speter Make a local copy of the line being sent via senttolist() -- in 612538032Speter some cases, buffers could get trashed by map lookups 612638032Speter causing it to do unexpected things. This also simplifies 612738032Speter some of the map code. 612838032Speter CONFIG: No changes (version number only, to keep it in sync 612938032Speter with the binaries). 613038032Speter 613164562Sgshapiro8.6.9/8.6.9 1994/04/19 613238032Speter Do all mail delivery completely disconnected from any terminal. 613338032Speter This provides consistency with daemon delivery and 613438032Speter may have some security implications. 613538032Speter Make sure that malloc doesn't get called with zero size, 613638032Speter since that fails on some systems. Reported by Ed 613738032Speter Hill of the University of Iowa. 613838032Speter Fix multi-line values for $e (SMTP greeting message). Reported 613938032Speter by Mike O'Connor of Ford Motor Company. 614038032Speter Avoid syserr if no NIS domain name is defined, but the map it 614138032Speter is trying to open is optional. From Win Bent of USC. 614238032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 614338032Speter Hesiod support for UDB from Todd Miller of the University of 614438032Speter Colorado. Use "hesiod" as the service name in the U 614538032Speter option. 614638032Speter Fix a problem that failed to set the "authentic" host name (that 614738032Speter is, the one derived from the socket info) if you called 614838032Speter sendmail -bs from inetd. Based on code contributed by 614938032Speter Todd Miller (this problem was also reported by Guy Helmer 615038032Speter of Dakota State University). This also fixes a related 615138032Speter problem reported by Liudvikas Bukys of the University of 615238032Speter Rochester. 615338032Speter Parameterize "nroff -h" in all the Makefiles so people with 615438032Speter variant versions can use them easily. Suggested by 615538032Speter Peter Collinson of Hillside Systems. 615638032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 615738032Speter spaces between parameters instead of one. Reported by 615838032Speter Valdis Kletnieks of Virginia Tech. 615938032Speter Reduce the number of system calls during message collection by 616038032Speter using global timeouts around the collect() loop. This 616138032Speter code was contributed by Eric Wassenaar. 616238032Speter If the initial hostname name gathering results in a name 616338032Speter without a dot (usually caused by NIS misconfiguration) 616438032Speter and BIND is compiled in, directly access DNS to get 616538032Speter the canonical name. This should make life easier for 616638032Speter Solaris systems. If it still can't be resolved, and 616738032Speter if the name server is listed as "required", try again 616838032Speter in 30 seconds. If that also fails, exit immediately to 616938032Speter avoid bogus "config error: mail loops back to myself" 617038032Speter messages. 617138032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 617238032Speter message to explain how much space was available and 617338032Speter sound a bit less threatening. Suggested by Stan Janet 617438032Speter of the National Institute of Standards and Technology. 617538032Speter If mail is delivered to an alias that has an owner, deliver any 617638032Speter requested return-receipt immediately, and strip the 617738032Speter Return-Receipt-To: header from the subsequent message. 617838032Speter This prevents a certain class of denial of service 617938032Speter attack, arguably gives more reasonable semantics, and 618038032Speter moves things more towards what will probably become a 618138032Speter network standard. Suggested by Christopher Davis of 618238032Speter Kapor Enterprises. 618338032Speter Add a "noreceipts" privacy flag to turn off all return receipts 618438032Speter without recompiling. 618538032Speter Avoid printing ESMTP parameters as part of the error message 618638032Speter if there are errors during parsing. This change is 618738032Speter purely cosmetic. 618838032Speter Avoid sending out error messages during the collect phase of 618938032Speter SMTP; there is an MVS mailer from UCLA that gets 619038032Speter confused by this. Of course, I think it's their bug.... 619138032Speter Check for the $j macro getting undefined, losing a dot, or getting 619238032Speter lost from $=w in the daemon before accepting a connection; 619338032Speter if it is, it dumps state, prints a LOG_ALERT message, 619438032Speter and drops core for debugging. This is an attempt to 619538032Speter track down a bug that I thought was long since gone. 619638032Speter If you see this, please forward the log fragment to 619738032Speter sendmail@sendmail.ORG. 619838032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 619938032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 620038032Speter Wolfhugel. 620138032Speter Instead of trying to truncate the listen queue for the server 620238032Speter SMTP port when the load average is too high, just close 620338032Speter the port completely and reopen it later as needed. 620438032Speter This ensures that the other end gets a quick "connection 620538032Speter refused" response, and that the connection can be 620638032Speter recovered later. In particular, some socket emulations 620738032Speter seem to get confused if you tweak the listen queue 620838032Speter size around and can never start listening to connections 620938032Speter again. The down side is that someone could start up 621038032Speter another daemon process in the interim, so you could 621138032Speter have multiple daemons all not listening to connections; 621238032Speter this could in turn cause the sendmail.pid file to be 621338032Speter incorrect. A better approach might be to accept the 621438032Speter connection and give a 421 code, but that could break 621543730Speter other mailers in mysterious ways and have paging behavior 621638032Speter implications. 621738032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 621838032Speter set debugging on the wrong socket. From Eric Wassenaar. 621938032Speter When creating a df* temporary file, be sure you truncate any 622038032Speter existing data in the file -- otherwise system crashes 622138032Speter and the like could result in extra data being sent. 622238032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 622338032Speter doc directory. This includes some additional 622438032Speter information. 622538032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 622638032Speter of recipient envelope addresses. This should have been 622738032Speter handled by the $&h trick, but broke if people were 622838032Speter mixing domainized and UUCP addresses. They should 622938032Speter probably have converted all the way over to uucp-uudom 623038032Speter instead of uucp-{new,old}, but the failure mode was to 623138032Speter loop the mail, which was bad news. 623238032Speter Portability fixes: 623338032Speter Newer BSDI systems (several people). 623438032Speter Older BSDI systems from Christophe Wolfhugel. 623538032Speter Intergraph CLIX, from Paul Southworth of CICNet. 623638032Speter UnixWare, from Evan Champion. 623738032Speter NetBSD from Adam Glass. 623838032Speter Solaris from Quentin Campbell of the University of 623938032Speter Newcastle upon Tyne. 624038032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 624138032Speter Corporation. 624238032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 624338032Speter SunOS (it has setsid() and setvbuf() calls) from 624438032Speter Jonathan Kamens of OpenVision Technologies. 624538032Speter HP-UX from Tor Lillqvist. 624638032Speter New Files: 624738032Speter src/Makefile.CLIX 624838032Speter src/Makefile.NCR3000 624938032Speter doc/changes/Makefile 625038032Speter doc/changes/changes.me 625138032Speter doc/changes/changes.ps 625238032Speter 625364562Sgshapiro8.6.8/8.6.6 1994/03/21 625438032Speter SECURITY: it was possible to read any file as root using the 625538032Speter E (error message) option. Reported by Richard Jones; 625638032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 625738032Speter 625864562Sgshapiro8.6.7/8.6.6 1994/03/14 625938032Speter SECURITY: it was possible to get root access by using weird 626038032Speter values to the -d flag. Thanks to Alain Durand of 626138032Speter INRIA for forwarding me the notice from the bugtraq 626238032Speter list. 626338032Speter 626464562Sgshapiro8.6.6/8.6.6 1994/03/13 626538032Speter SECURITY: the ability to give files away on System V-based 626638032Speter systems proved dangerous -- don't run as the owner 626738032Speter of a :include: file on a system that allows giveaways. 626838032Speter Unfortunately, this also applies to determining a 626938032Speter valid shell. 627038032Speter IMPORTANT: Previous versions weren't expiring old connections 627138032Speter in the connection cache for a long time under some 627238032Speter circumstances. This could result in resource exhaustion, 627338032Speter both at your end and at the other end. This checks the 627438032Speter connections for timeouts much more frequently. From 627538032Speter Doug Anderson of NCSC. 627638032Speter Fix a glitch that snuck in that caused programs to be run as 627738032Speter the sender instead of the recipient if the mail was 627838032Speter from a local user to another local user. From 627938032Speter Motonori Nakamura of Kyoto University. 628038032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 628138032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 628238032Speter Bryan Costales of ICSI. 628338032Speter Change the method used to declare the "statfs" availability; 628438032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 628538032Speter tweaking in conf.c, there is a single #define called 628638032Speter SFS_TYPE which takes on one of six values (SFS_NONE 628738032Speter for no statfs availability, SFS_USTAT for the ustat(2) 628838032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 628938032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 629038032Speter statfs(2) call with the declarations in <sys/vfs.h>, 629138032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 629238032Speter Fix glitch in NetInfo support that could return garbage if 629338032Speter there was no "/locations/sendmail" property. From 629438032Speter David Meyer of the University of Virginia. 629538032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 629638032Speter to allow Linux to turn it off even though it is a 629738032Speter BSD-like system. 629838032Speter Allow setting of "ident" timeout to zero to turn off the ident 629938032Speter protocol entirely. 630038032Speter Make 7-bit stripping local to a connection (instead of to a 630138032Speter mailer); this allows you to specify that SMTP is a 630238032Speter 7-bit channel, but revert to 8-bit should it advertise 630338032Speter that it supports 8BITMIME. You still have to specify 630438032Speter mailer flag 7 to get this stripping at all. 630538032Speter Improve makesendmail script so it handles more cases automatically. 630638032Speter Tighten up restrictions on taking ownership of :include: files 630738032Speter to avoid problems on systems that allow you to give away 630838032Speter files. 630938032Speter Fix a problem that made it impossible to rebuild the alias 631038032Speter file if it was on a read-only file system. From 631138032Speter Harry Edmon of the University of Washington. 631238032Speter Improve MX randomization function. From John Gardiner Myers 631338032Speter of CMU. 631438032Speter Fix a minor glitch causing a bogus message to be printed (used 631538032Speter %s instead of %d in a printf string for the line number) 631638032Speter when a bad queue file was read. From Harry Edmon. 631738032Speter Allow $s to remain NULL on locally generated mail. I'm not 631838032Speter sure this is necessary, but a lot of people have complained 631938032Speter about it, and there is a legitimate question as to whether 632038032Speter "localhost" is legal as an 822-style domain. 632138032Speter Fix a problem with very short line lengths (mailer L= flag) in 632238032Speter headers. This causes a leading space to be added onto 632338032Speter continuation lines (including in the body!), and also 632438032Speter tries to wrap headers containing addresses (From:, To:, 632538032Speter etc) intelligently at the shorter line lengths. Problem 632638032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 632738032Speter Log the real user name when logging syserrs, since these can have 632838032Speter security implications. Suggested by several people. 632938032Speter Fix address logging of cached connections -- it used to always 633038032Speter log the numeric address as zero. This is a somewhat 633138032Speter bogus implementation in that it does an extra system 633238032Speter call, but it should be an inexpensive one. Fix from 633338032Speter Motonori Nakamura. 633438032Speter Tighten up handling of short syslog buffers even more -- there 633538032Speter were cases where the outgoing relay= name was too long 633638032Speter to share a line with delay= and mailer= logging. 633738032Speter Limit the overhead on split envelopes to one open file descriptor 633838032Speter per envelope -- previously the overhead was three 633938032Speter descriptors. This was in response to a problem reported 634038032Speter by P{r (Pell) Emanuelsson. 634138032Speter Fixes to better handle the case of unexpected connection closes; 634238032Speter this redirects the output to the transcript so the info 634338032Speter is not lost. From Eric Wassenaar. 634438032Speter Fix potential string overrun if you macro evaluate a string that 634538032Speter has a naked $ at the end. Problem noted by James Matheson 634638032Speter <jmrm@eng.cam.ac.uk>. 634738032Speter Make default error number on $#error messages 553 (``Requested 634838032Speter action not taken: mailbox name not allowed'') instead of 634938032Speter 501 (``Syntax error in parameters or arguments'') to 635038032Speter avoid bogus "protocol error" messages. 635138032Speter Strip off any existing trailing dot on names during $[ ... $] 635238032Speter lookup. This prevents it from ending up with two dots 635338032Speter on the end of dot terminated names. From Wesley Craig 635438032Speter of the University of Michigan and Bryan Costales of ICSI. 635538032Speter Clean up file class reading so that the debugging information is 635638032Speter more informative. It hadn't been using setclass, so you 635738032Speter didn't see the class items being added. 635838032Speter Avoid core dump if you are running a version of sendmail where 635938032Speter NIS is compiled in, and you specify an NIS map, but 636038032Speter NIS is not running. Fix from John Oleynick of 636138032Speter Rutgers. 636238032Speter Diagnose bizarre case where res_search returns a failure value, 636338032Speter but sets h_errno to a success value. 636438032Speter Make sure that "too many hops" messages are considered important 636538032Speter enough to send an error to the Postmaster (that is, the 636638032Speter address specified in the P option). This fix should 636738032Speter help problems that cause the df file to be left around 636838032Speter sometimes -- unfortunately, I can't seem to reproduce 636938032Speter the problem myself. 637038032Speter Avoid core dump (null pointer reference) on EXPN command; this 637138032Speter only occurred if your log level was set to 10 or higher 637238032Speter and the target account was an alias or had a .forward file. 637338032Speter Problem noted by Janne Himanka. 637438032Speter Avoid "denial of service" attacks by someone who is flooding your 637538032Speter SMTP port with bad commands by shutting the connection 637638032Speter after 25 bad commands are issued. From Kyle Jones of 637738032Speter UUNET. 637838032Speter Fix core dump on error messages with very long "to" buffers; 637938032Speter fmtmsg overflows the message buffer. Fixed by trimming 638038032Speter the to address to 203 characters. Problem reported by 638138032Speter John Oleynick. 638238032Speter Fix configuration for HASFLOCK -- there were some spots where 638338032Speter a #ifndef was incorrectly #ifdef. Pointed out by 638438032Speter George Baltz of the University of Maryland. 638538032Speter Fix a typo in savemail() that could cause the error message To: 638638032Speter lists to be incorrect in some places. From Motonori 638738032Speter Nakamura. 638838032Speter Fix a glitch that can cause duplicate error messages on split 638938032Speter envelopes where an address on one of the lists has a 639038032Speter name server failure. Fix from Voradesh Yenbut of the 639138032Speter University of Washington. 639238032Speter Fix possible bogus pointer reference on ESMTP parameters that 639338032Speter don't have an ``=value'' part. 639438032Speter CNAME loops caused an error message to be generated, but also 639538032Speter re-queued the message. Changed to just re-queue the 639638032Speter message (it's really hard to just bounce it because 639738032Speter of the weird way the name server works in the presence 639838032Speter of CNAME loops). Problem noted by James M.R.Matheson 639938032Speter of Cambridge University. 640038032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 640138032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 640238032Speter user name. Suggested by Andreas Stolcke of ICSI. 640338032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 640438032Speter override it easily in the Makefile -- that is, you can 640538032Speter turn it off using -DNAMED_BIND=0. 640638032Speter If a gethostbyname(...) of an address with a trailing dot fails, 640738032Speter try it without the trailing dot. This is because if 640838032Speter you have a version of gethostbyname() that falls back 640938032Speter to NIS or the /etc/hosts file it will fail to find 641038032Speter perfectly reasonable names that just don't happen to 641138032Speter be dot terminated in the hosts file. You don't want to 641238032Speter strip the dot first though because we're trying to ensure 641338032Speter that country names that match one of your subdomains get 641438032Speter a chance. 641538032Speter PRALIASES: fix bogus output on non-null-terminated strings. 641638032Speter From Bill Gianopoulos of Raytheon. 641738032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 641838032Speter This was in code intended to only catch the self-literal 641938032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 642038032Speter IP address), but the code was broken. However, it will 642138032Speter still do this if $M is defined; this is necessary to 642238032Speter get client configurations to work (sigh). Note that this 642338032Speter means that $M overrides :mailname entries in the user 642438032Speter database! Problem noted by Paul Southworth. 642538032Speter CONFIG: Fix definition of Solaris help file location. From 642638032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 642738032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 642838032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 642938032Speter and USENET_MAILER_MAX to tweak the maximum message 643038032Speter size for various mailers. 643138032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 643238032Speter instead of assuming that it is "inews" for consistency 643338032Speter with other mailers. From Michael Corrigan of UC San Diego. 643438032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 643538032Speter qualify the address in the SMTP envelope as user@{relay|hub} 643638032Speter instead of user@$j. From Bill Wisner of The Well. 643738032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 643838032Speter CONFIG: Don't turn off case mapping of user names in the local 643938032Speter mailer for IRIX. This was different than most every other 644038032Speter system. 644138032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 644238032Speter envelope. Noted by Thierry Besancon 644338032Speter <besancon@excalibur.ens.fr>. 644438032Speter CONFIG: Don't include -z by default on uux line -- most systems 644538032Speter don't want it set by default. Pointed out by Philippe 644638032Speter Michel of Thomson CSF. 644738032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 644838032Speter host name was foo.bar.ray.com and you matched against 644938032Speter ".ray.com", the old implementation bound %1 to "bar" 645038032Speter instead of "foo.bar". Also, allow "." in the mailertable 645138032Speter to match anything -- essentially, take over SMART_HOST. 645238032Speter This also moves matching of explicit local host names 645338032Speter before the mailertable so they don't have to be special 645438032Speter cased in the mailertable data. Reported by Bill 645538032Speter Gianopoulos of Raytheon; the fix for the %1 binding 645638032Speter problem was contributed by Nicholas Comanos of the 645738032Speter University of Sydney. 645838032Speter CONFIG: Don't include "root" in class $=L (users to deliver 645938032Speter locally, even if a hub or relay exists) by default. 646038032Speter This is because of the known bug where definition of 646138032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 646238032Speter both and deliver into the local mailbox. 646338032Speter CONFIG: Move up bitdomain and uudomain handling so that they 646438032Speter are done before .UUCP class matching; uudomain was 646538032Speter reported as ineffective before. This also frees up 646638032Speter diversion 8 for future use. Problem reported by Kimmo 646738032Speter Suominen. 646838032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 646938032Speter into host names. As pointed out by Jonathan Kamens, 647038032Speter these are often used because either the forward or reverse 647138032Speter mapping is broken; this translation makes it broken again. 647238032Speter DOC: Clarify $@ and $: in the Install & Op Guide.

From 649938032Speter Bob Campbell at U.C. Berkeley. 650038032Speter Security fix: group ids were not completely set when programs 650138032Speter were invoked. This caused programs to have group 650238032Speter permissions they should not have had (usually group 650338032Speter daemon instead of their own group). In particular, 650438032Speter Perl scripts would refuse to run. 650538032Speter Security: check to make sure files that are written are not 650638032Speter symbolic links (at least under some circumstances). 650738032Speter Although this does not respond to a specific known 650838032Speter attack, it's just a good idea. Suggested by 650938032Speter Christian Wettergren. 651038032Speter Security fix: if a user had an NFS mounted home directory on 651138032Speter a system with a restricted shell listed in their 651238032Speter /etc/passwd entry, they could still execute any 651338032Speter program by putting that in their .forward file. 651438032Speter This fix prevents that by insisting that their shell 651538032Speter appear in /etc/shells before allowing a .forward to 651638032Speter execute a program or write a file. You can disable 651738032Speter this by putting "*" in /etc/shells. It also won't 651838032Speter permit world-writable :include: files to reference 651938032Speter programs or files (there's no way to disable this). 652043730Speter These behaviors are only one level deep -- for 652138032Speter example, it is legal for a world-writable :include: 652238032Speter file to reference an alias that writes a file, on 652338032Speter the assumption that the alias file is well controlled. 652438032Speter Security fix: root was not treated suspiciously enough when 652538032Speter looking into subdirectories. This would potentially 652638032Speter allow a cracker to examine files that were publicly 652738032Speter readable but in a non-publicly searchable directory. 652838032Speter Fix a problem that causes an error on QUIT on a cached 652938032Speter connection to create problems on the current job. 653038032Speter These are typically unrelated, so errors occur in 653138032Speter the wrong place. 653238032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 653338032Speter runs more responsive to load average, and fixes a 653438032Speter problem that ignored the load average in locally 653538032Speter generated mail. From Eric Wassenaar. 653638032Speter Fix possible core dump on aliases with null LHS. From 653738032Speter John Orthoefer of BB&N. 653838032Speter Revert to using flock() whenever possible -- there are just 653938032Speter too many bugs in fcntl() locking, particularly over 654038032Speter NFS, that cause sendmail to fail in perverse ways. 654138032Speter Fix a bug that causes the connection cache to get confused 654238032Speter when sending error messages. This resulted in 654338032Speter "unexpected close" messages. It should fix itself 654438032Speter on the following queue run. Problem noted by 654538032Speter Liudvikas Bukys of the University of Rochester. 654638032Speter Include $k in $=k as documented in the Install & Op Guide. 654738032Speter This seems odd, but it was documented.... From 654838032Speter Michael Corrigan of UCSD. 654938032Speter Fix problem that caused :include:s from alias files to be 655038032Speter forced to be owned by root instead of daemon 655138032Speter (actually DefUid). From Tim Irvin. 655238032Speter Diagnose unrecognized I option values -- from Mortin Forssen 655338032Speter of the Chalmers University of Technology. 655438032Speter Make "error" mailer work consistently when there is no error 655538032Speter code associated with it -- previously it returned OK 655638032Speter even though there was a real problem. Now it assumes 655738032Speter EX_UNAVAILABLE. 655838032Speter Fix bug that caused the last header line of messages that had 655938032Speter no body and which were terminated with EOF instead of 656038032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 656138032Speter Fix core dump on SMTP mail to programs that failed -- it tried 656238032Speter to go to a "next MX host" when none existed, causing 656338032Speter a core dump. From der Mouse at McGill University. 656438032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 656538032Speter this makes it easier to turn it off (using 656638032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 656738032Speter Fix YP_MASTER_NAME store to use the unupdated result of 656838032Speter gethostname() (instead of myhostname(), which tries 656938032Speter to fully qualify the name) to be consistent with 657038032Speter SunOS. If your hostname is unqualified, this fixes 657138032Speter transfers to slave servers. Bug noted by Keith 657238032Speter McMillan of Ameritech Services, Inc. 657338032Speter Fix Ultrix problem: gethostbyname() can return a very large 657438032Speter (> 500) h_length field, which causes the sockaddr 657538032Speter to be trashed. Use the size of the sockaddr instead. 657638032Speter Fix from Bob Manson of Ohio State. 657738032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 657838032Speter defined -- this confuses gethostbyname on hosts 657938032Speter file lookups, which doesn't understand the trailing 658038032Speter dot convention. 658138032Speter Log SMTP server subprocesses that die with a signal instead 658238032Speter of from a clean exit. 658338032Speter If you don't have option "I" set, don't assume that a DNS 658438032Speter "host unknown" message is authoritative -- it 658538032Speter might still be found in /etc/hosts. 658638032Speter Fix a problem that would cause Deferred: messages to be sent 658738032Speter as the subject of an error message, even though the 658838032Speter actual cause of a message was more severe than that. 658938032Speter Problem noted by Chris Seabrook of OSSI. 659038032Speter Fix race condition in DBM alias file locking. From Kyle 659138032Speter Jones of UUNET. 659238032Speter Limit delivery syslog line length to avoid bugs in some 659338032Speter versions of syslog(3). This adds a new compile time 659438032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 659538032Speter University, which is in turn derived from IDA. 659638032Speter Fix quotes inside of comments in addresses -- previously 659738032Speter it insisted that they be balanced, but the 822 spec 659838032Speter says that they should be ignored. 659938032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 660038032Speter debugging). This also evaluates ruleset 89, if set 660138032Speter (with the null input), and logs the result. This 660238032Speter should be used sparingly, since the rewrite process 660338032Speter is not reentrant. 660438032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 660538032Speter documented in the Bat Book. 660638032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 660738032Speter return an error message and did not requeue the message. 660838032Speter Fix based on code from Roland Dirlewanger of 660938032Speter Reseau Regional Aquarel, Bordeaux, France. 661038032Speter Fix a problem that caused a seg fault if you got a 421 error 661138032Speter code during some parts of connection initialization. 661238032Speter I've only seen this when talking to buggy mailers on 661338032Speter the other end, but it shouldn't give a seg fault in 661438032Speter any case. From Amir Plivatsky. 661538032Speter Fix core dump caused by a ruleset call that returns null. 661638032Speter Fix from Bryan Costales of ICSI. 661738032Speter Full-Name: field was being ignored.

Suggested by 662438032Speter Bryan Costales. 662538032Speter Initialize non-alias maps during alias rebuilds -- they may be 662638032Speter needed for parsing. Problem noted by Douglas Anderson. 662738032Speter Log sender address even if no message was collected in SMTP 662838032Speter (e.g., if all RCPTs failed). Suggested by Motonori 662938032Speter Nakamura. 663038032Speter Don't reflect the owner-list contents into the envelope sender 663138032Speter address if the value contains ", :, /, or | (to avoid 663238032Speter illegal addresses appearing there). 663338032Speter Efficiency hack for toktype macro -- from Craig Partridge of 663438032Speter BB&N. 663538032Speter Clean up DNS error printing so that a host name is always 663638032Speter included. 663738032Speter Remember to set $i during queue runs. Reported by Stephen 663838032Speter Campbell of Dartmouth University. 663938032Speter If the environment variable HOSTALIASES is set, use it during 664038032Speter canonification as the name of a file with per-user host 664138032Speter translations so that headers are properly mapped.

From 664738032Speter Dave Morrison of Oracle. 664838032Speter Improve several of the error messages printed by "mailq" 664938032Speter to include a host name or other useful information. 665038032Speter Add NetInfo preliminary support for NeXT systems. From Vince 665138032Speter DeMarco. 665238032Speter Fix a glitch that sometimes caused :include:s that pointed to 665338032Speter NFS filesystems that were down to give an "aliasing/ 665438032Speter forwarding loop broken" message instead of queueing 665538032Speter the message for retry. Noted by William C Fenner of 665638032Speter the NRL Connection Machine Facility. 665738032Speter Fix a problem that could cause a core dump if the input sequence 665838032Speter had (or somehow acquired) a \231 character. 665938032Speter Make sure that route-addrs always have <angle brackets> around 666038032Speter them in non-SMTP envelopes (SMTP envelopes already do 666138032Speter this properly). 666238032Speter Avoid weird headers on unbalanced punctuation of the form: 666338032Speter ``Joe User <user)'' -- this caused reference to the 666438032Speter null macro. Fix from Rick McCarty of IO.COM. 666538032Speter Fix a problem that caused an alias "user: user@local.host" to 666638032Speter not have the QNOTREMOTE bit set; this caused configs 666738032Speter to act as if FEATURE(notsticky) was defined even when 666838032Speter it was not. The effect of the problem was to make it 666938032Speter very hard to to set up satellite sites that had a few 667038032Speter local accounts, with everything else forwarded to a 667138032Speter corporate hub. Reported by Detlef Drewanz of the 667238032Speter University of Rostock and Mark Frost of NCD. 667338032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 667438032Speter addresses. This is more efficient (fewer name server 667538032Speter calls) and fixes certain unusual configurations, such 667638032Speter as those that have ruleset 4 do something that is 667738032Speter non-idempotent unless a mailer-specific ruleset did 667838032Speter something else. Problem reported by Brian J. Coan 667938032Speter of the Institute for Global Communications. 668038032Speter Fix the "obsolete argument" routine in main to better understand 668138032Speter new arguments.

Briefly, if you are sending to host 674738032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 674838032Speter "foo!baz" remains "foo!baz", and anything else has 674938032Speter the local name prepended. 675038032Speter CONFIG: portability fixes for HP-UX. 675138032Speter DOC: several minor problems fixed in the Install & Op Guide. 675238032Speter MAKEMAP: fix core dump problem on lines that are too long or 675338032Speter which lack newline. From Mark Delany. 675438032Speter MAILSTATS: print sums of columns (total messages & kbytes 675538032Speter in and out of the system). From Tom Ferrin of UC 675638032Speter San Francisco Computer Graphics Lab. 675738032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 675838032Speter On HP-UX, /etc/sendmail.cf has been moved to 675938032Speter /usr/lib/sendmail.cf to match HP sendmail. 676038032Speter Permissions have been tightened up on world-writable 676138032Speter :include: files and accounts that have shells 676238032Speter that are not listed in /etc/shells. This may 676338032Speter cause some .forward files that have worked 676438032Speter before to start failing. 676538032Speter SIGUSR1 dumps some state to the log. 676638032Speter NEW FILES: 676738032Speter src/Makefile.DGUX 676838032Speter src/Makefile.Dynix 676938032Speter src/Makefile.FreeBSD 677038032Speter src/Makefile.Mach386 677138032Speter src/Makefile.NetBSD 677238032Speter src/Makefile.RISCos 677338032Speter src/Makefile.SCO 677438032Speter src/Makefile.SVR4 677538032Speter src/Makefile.Titan 677638032Speter cf/mailer/pop.m4 677738032Speter cf/ostype/bsdi1.0.m4 677838032Speter cf/ostype/dgux.m4 677938032Speter cf/ostype/dynix3.2.m4 678038032Speter cf/ostype/sco3.2.m4 678138032Speter makemap/Makefile.dist 678238032Speter praliases/Makefile.dist 678338032Speter 678464562Sgshapiro8.6.4/8.6.4 1993/10/31 678538032Speter Repair core-dump problem (write to read-only memory segment) 678638032Speter if you fall back to the return-to-Postmaster case in 678738032Speter savemail. Problem reported by Richard Liu. 678838032Speter Immediately diagnose bogus sender addresses in SMTP. This 678938032Speter makes quite certain that crackers can't use this 679038032Speter class of attack. 679138032Speter Reliability Fix: check return value from fclose() and fsync() 679238032Speter in a few critical places. 679338032Speter Minor problem in initsys() that reversed a condition for 679438032Speter redirecting the output channel on queue runs. It's 679538032Speter not clear this code even does anything. From Eric 679638032Speter Wassenaar of the Dutch National Institute for Nuclear 679738032Speter and High-Energy Physics. 679838032Speter Fix some problems that caused queue runs to do "too much work", 679938032Speter such as double-reading the Errors-To: header. From 680038032Speter Eric Wassenaar. 680138032Speter Error messages on writing the temporary file (including the 680238032Speter data file) were getting suppressed in SMTP -- this 680338032Speter fix causes them to be properly reported. From Eric 680438032Speter Wassenaar. 680538032Speter Some changes to support AF_UNIX sockets -- this will only 680638032Speter really become relevant in the next release, but some 680738032Speter people need it for local patches. From Michael 680838032Speter Corrigan of UC San Diego. 680938032Speter Use dynamically allocated memory (instead of static buffers) 681038032Speter for macros defined in initsys() and settime(); since 681138032Speter these can have different values depending on which 681238032Speter envelope they are in. From Eric Wassenaar. 681338032Speter Improve logging to show ctladdr on to= logging; this tells you 681438032Speter what uid/gid processes ran as. 681538032Speter Fix a problem that caused error messages to be discarded if 681638032Speter the sender address was unparseable for some reason; 681738032Speter this was supposed to fall back to the "return to 681838032Speter postmaster" case. 681938032Speter Improve aliaswait backoff algorithm. 682038032Speter Portability patches for Linux (8.6.3 required another header 682138032Speter file) (from Karl London) and SCO UNIX. 682238032Speter CONFIG: patch prog mailer to not strip host name off of envelope 682338032Speter addresses (so that it matches local again). From 682438032Speter Christopher Davis. 682538032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 682638032Speter this prevents uux from seeing lines with null names like 682738032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 682838032Speter Nakamura of Kyoto University. 682938032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 683038032Speter it shouldn't fail miserably. From Motonori Nakamura. 683138032Speter 683264562Sgshapiro8.6.2/8.6.2 1993/10/15 683338032Speter Put a "successful delivery" message in the transcript for 683438032Speter addresses that get return-receipts. 683538032Speter Put a prominent "this is only a warning" message in warning 683638032Speter messages -- some people don't read carefully enough 683738032Speter and end up sending the message several times. 683838032Speter Include reason for temporary failure in the "warning" return 683938032Speter message. Currently, it just says "cannot send for 684038032Speter four hours". 684138032Speter Fix the "Original message received" time generated for 684238032Speter returntosender messages. It was previously listed as 684338032Speter the current time. Bug reported by Eric Hagberg of 684438032Speter Cornell University Medical College. 684538032Speter If there is an error when writing the body of a message, 684638032Speter don't send the trailing dot and wait for a response 684738032Speter in sender SMTP, as this could cause the connection to 684838032Speter hang up under some bizarre circumstances. From Eric 684938032Speter Wassenaar. 685038032Speter Fix some server SMTP synchronization problems caused when 685138032Speter connections fail during message collection. From 685238032Speter Eric Wassenaar. 685338032Speter Fix a problem that can cause srvrsmtp to reject mail if the 685438032Speter name server is down -- it accepts the RCPT but rejects 685538032Speter the DATA command. Problem reported by Jim Murray of 685638032Speter Stratus. 685738032Speter Fix a problem that can cause core dumps if the config file 685838032Speter incorrectly resolves to a null hostname. Reported by 685938032Speter Allan Johannesen of WPI. 686038032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 686138032Speter by non-root users were not put into 686238032Speter X-Authentication-Warning:s as intended because the 686343730Speter config file hadn't set the PrivacyOptions yet. Fix 686438032Speter from Sven-Ove Westberg of the University of Lulea. 686538032Speter Under very odd circumstances, the alias file rebuild code 686638032Speter could get confused as to whether a database was 686738032Speter open or not. 686838032Speter Check "vendor code" on the end of V lines -- this is 686938032Speter intended to provide a hook for vendor-specific 687038032Speter configuration syntax. (This is a "new feature", 687138032Speter but I've made an exception to my rule in a belief 687238032Speter that this is a highly exceptional case.) 687338032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 687438032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 687538032Speter (from Jon Forrest of UC Berkeley) 687638032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 687738032Speter 687864562Sgshapiro8.6.1/8.6 1993/10/08 687938032Speter Portability fixes for A/UX and Encore UMAX V. 688038032Speter Fix error message handling -- if you had a name server down 688138032Speter causing an error during parsing, that message was never 688238032Speter propagated to the queue file. 688338032Speter 688464562Sgshapiro8.6/8.6 1993/10/05 688538032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 688638032Speter conf.h (other systems have the same bug). 688738032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 688838032Speter getdtablesize() instead of sysconf(); a disturbingly 688938032Speter large number of systems defined _SC_OPEN_MAX in the 689038032Speter header files but don't have the syscall. 689138032Speter Another patch to really truly ignore MX records in getcanonname 689238032Speter if trymx == FALSE. 689338032Speter Fix problem that caused the "250 IAA25499 Message accepted for 689438032Speter delivery" message to be omitted if there was an error 689538032Speter in the header of the message (e.g., a bad Errors-To: 689638032Speter line). Pointed out by Michael Corrigan of UCSD. 689738032Speter Announce name of host we are chatting when we get errors; this 689838032Speter is an IDA-ism suggested by Christophe Wolfhugel. 689938032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 690038032Speter Australian Artificial Intelligence Institute), SCO Unix 690138032Speter (from Murray Kucherawy of Hookup Communication Corp.), 690238032Speter NeXT (from Vince DeMarco and myself), Linux (from 690338032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 690438032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 690538032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 690638032Speter Some changes to get around gcc optimizer bugs. From Takahiro 690738032Speter Kanbe. 690838032Speter Fix error recovery in queueup if another tf file of the same 690938032Speter name already exists. Problem stumbled over by Bill 691038032Speter Wisner of The Well. 691138032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 691238032Speter Problem noted by Keith McMillan of Ameritech Services. 691338032Speter Deal with group permissions properly when opening .forward and 691438032Speter :include: files. This relaxes the 8.1C restrictions 691538032Speter slightly more. This includes proper setting of groups 691638032Speter when reading :include: files, allowing you to read some 691738032Speter files that you should be able to read but have previously 691838032Speter been denied unless you owned them or they had "other" 691938032Speter read permission. 692038032Speter Make certain that $j is in $=w (after the .cf is read) so that 692138032Speter if the user is forced to override some silly system, 692238032Speter MX suppression will still work. 692338032Speter Fix a couple of efficiency problems where newstr was double- 692438032Speter calling expensive routines. In at least one case, it 692538032Speter wasn't guaranteed that they would always return the 692638032Speter same result. Problem noted by Christophe Wolfhugel. 692738032Speter Fix null pointer dereference in putoutmsg -- only on an error 692838032Speter condition from a non-SMTP mailer. From Motonori 692938032Speter Nakamura. 693038032Speter Macro expand "C" line class definitions before scanning so that 693138032Speter "CX $Z" works. 693238032Speter Fix problem that caused error message to be sent while still 693338032Speter trying to send the original message if the connection 693438032Speter is closed during a DATA command after getting an error 693538032Speter on an RCPT command (pretty obscure). Problem reported 693638032Speter by John Myers of CMU. 693738032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 693838032Speter term bug. 693938032Speter Fix a nasty bug causing core dumps when returning the "warning: 694038032Speter cannot deliver for N hours -- will keep trying" message; 694143730Speter it only occurred if you had PostmasterCopy set and 694238032Speter only on some architectures. Although sendmail would 694338032Speter keep trying, it would send error messages on each 694438032Speter queue interval. This is an important fix. 694538032Speter Allow u and g options to take user and group names respectively. 694638032Speter Don't do a chdir into the queue directory in -bt mode to make 694738032Speter ruleset testing a bit easier. 694838032Speter Don't allow users to turn off logging (using -oL) on the command 694938032Speter line -- command line can only raise, not lower, logging 695038032Speter level. 695138032Speter Set $u to the original recipient on the SMTP transaction or on 695238032Speter the command line. This is only done if there is exactly 695338032Speter one recipient. Technically, this does not meet the 695438032Speter specs, because it does not guarantee a domain on the 695538032Speter address. 695638032Speter Fix a problem that dumped error messages on bad addresses if 695738032Speter you used the -t flag. Problem noted by Josh Smith of 695838032Speter Harvey Mudd College. 695938032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 696038032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 696138032Speter avoid the problem of people who use angle brackets in 696238032Speter their full name information. 696338032Speter Fix a null pointer dereference if you set option "l", have 696438032Speter an Errors-To: header in the message, and have Errors-To: 696538032Speter defined in the config file H lines. From J.R. Oldroyd. 696638032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 696738032Speter wrong when compiling. Suggested by Rick McCarty of TI. 696838032Speter Fix a problem that could pass negative SIZE parameter if the 696938032Speter df file got lost; this would cause servers to always 697038032Speter give a temporary failure, making the problem even worse. 697138032Speter Problem noted by Allan Johannesen of WPI. 697238032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 697338032Speter protocol timeouts (30s default). Requested by Murray 697438032Speter Kucherawy of HookUp Communication Corp. to handle bogus 697538032Speter PC TCP/IP implementations. 697638032Speter Change $w default definition to be just the first component of 697738032Speter the domain name on config level 5. The $j macro defaults 697838032Speter to the FQDN; $m remains as before. This lets well-behaved 697938032Speter config files use any of the short, long, or subdomain 698038032Speter names. 698138032Speter Add makesendmail script in src to try to automate multi-architecture 698238032Speter builds. I know, this is sub-optimal, but it is still 698338032Speter helpful. 698438032Speter Fix very obscure race condition that can cause a queue run to 698538032Speter get a queue file for an already completed job. This 698638032Speter problem has existed for years. Problem noted by the 698738032Speter long suffering Allan Johannesen of WPI. 698838032Speter Fix a problem that caused the raw sender name to be passed to 698938032Speter udbsender instead of the canonified name -- this caused 699038032Speter it to sometimes miss records that it should have found. 699138032Speter Relax check of name on HELO packet so that a program using -bs 699238032Speter that claims to be itself works properly. 699338032Speter Restore rewriting of $: part of address through 2, R, 4 in 699438032Speter buildaddr -- this requires passing a lot of flags to get 699538032Speter it right. Unlike old versions, this ONLY rewrites 699638032Speter recipient addresses, not sender addresses. 699738032Speter Fix a bug that caused core dumps in config files that cannot 699838032Speter resolve /file/name style addresses. Fix from Jonathan 699938032Speter Kamens of OpenVision Technologies. 700038032Speter Fix problem with fcntl locking that can cause error returns to 700138032Speter be lost if the lock is lost; this required fully 700238032Speter queueing everything, dropping the envelope (so errors 700338032Speter would get returned), and then re-reading the queue from 700438032Speter scratch. 700538032Speter Fix a problem that caused aliases that redefine an otherwise 700638032Speter true address to still send to the original address 700738032Speter if and only if the alias failed in certain bizarre 700838032Speter ways (e.g, if they pointed at a list:; syntax address). 700938032Speter Problem pointed out by Jonathan Kamens. 701038032Speter Remove support for frozen configuration files. They caused 701138032Speter more trouble than it was worth. 701238032Speter Fix problem that can cause error messages to get ignored when 701338032Speter using both -odb and -t flags. Problem noted by Rob 701438032Speter McNicholas at U.C. Berkeley. 701538032Speter Include all "normal" variations on hostname in $=w. For example, 701638032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 701738032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 701838032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 701938032Speter the queue. 702038032Speter Reset SmtpPhase global on initial connection creation so that 702138032Speter messages don't come out with stale information. 702238032Speter Pass an "ext" argument to lockfile so that error/log messages 702338032Speter will properly reflect the true filename being locked. 702438032Speter Put all [...] address forms into $=w -- this eliminates the need 702538032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 702638032Speter Myers of CMU. 702738032Speter Fix a bug that can cause qf files to be left around even after 702838032Speter an SMTP RSET command. Problem and fix from Michael 702938032Speter Corrigan. 703043730Speter Don't send a PostmasterCopy to errors when the Precedence: is 703138032Speter negative. Error reports still go to the envelope 703238032Speter sender address. 703338032Speter Add LA_SHORT for load averages. 703438032Speter Lock sendmail.st file when posting statistics. 703538032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 703638032Speter set the size of the TCP send and receive buffers; if you 703738032Speter run over a slow slip line you may need to set these down 703838032Speter (although it would be better to fix the SLIP implementation 703938032Speter so that it's not necessary to recompile every program 704038032Speter that does bulk data transfer). 704138032Speter Allow null defaults on $( ... $) lookups. Problem reported by 704238032Speter Amir Plivatsky. 704338032Speter Diagnose crufty S and V config lines. This resulted from an 704438032Speter observation that some people were using the SITE macro 704538032Speter without the SITECONFIG macro first, which was causing 704638032Speter bogus config files that were not caught. 704738032Speter Fix makemap -f flag to turn off case folding (it was turning it 704838032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 704938032Speter Fix a problem that caused multiple error messages to be sent if 705038032Speter you used "sendmail -t -oem -odb", your system uses fcntl 705138032Speter locking, and one of the recipient addresses is unknown. 705238032Speter Reset uid earlier in include() so that recursive .forwards or 705338032Speter :include:s don't use the wrong uid. 705438032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 705538032Speter called, the code to recover the descriptor was broken. 705638032Speter This sometimes (only sometimes) caused problems with the 705738032Speter alias file. Fix from Motonori Nakamura. 705838032Speter Fix a problem that caused aliaswait to go into infinite recursion 705938032Speter if the @:@ metasymbol wasn't found in the alias file. 706038032Speter Improve error message on newaliases if database files cannot be 706138032Speter opened or if running with no database format defined. 706238032Speter Do a better estimation of the size of error messages when NoReturn 706338032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 706438032Speter Fix a problem causing the "c" option (don't connect to expensive 706538032Speter mailers) to be ignored in SMTP. Problem noted and the 706638032Speter solution suggested by Robert Elz of The University of 706738032Speter Melbourne. 706838032Speter Improve connection caching algorithm by passing "[host]" to 706938032Speter hostsignature, which strips the square brackets and 707038032Speter returns the real name. This allows mailertable entries 707138032Speter to match regular entries. 707238032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 707338032Speter feature, even if it doesn't work right. 707438032Speter Catch and log attempts to try the "wiz" command in server SMTP. 707538032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 707638032Speter Be more generous at assigning $z to the home directory -- do this 707738032Speter for programs that are specified through a .forward file. 707838032Speter Fix from Andrew Chang of Sun Microsystems. 707938032Speter Always save a fatal error message in preference to a non-fatal 708038032Speter error message so that the "subject" line of return 708138032Speter messages is the best possible. 708238032Speter CONFIG: reduce the number of quotes needed to quote configuration 708338032Speter parameters with commas: two quotes should work now, e.g., 708438032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 708538032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 708638032Speter connections (domain-ized UUCP). 708738032Speter CONFIG: fix bug in default maps (-o must be before database file 708864562Sgshapiro name). Pointed out by Christophe Wolfhugel. 708938032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 709038032Speter DNS. This would presumably be used in UUCP islands. 709138032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 709238032Speter CONFIG: log $u in Received: line. This is in technical violation 709338032Speter of the standards, since it doesn't guarantee a domain 709438032Speter on the address. 709538032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 709638032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 709738032Speter the "m" flag should you want it. Apparently some Solaris 2.2 709838032Speter installations can't handle multiple local recipients. 709938032Speter Problem noted by Josh Smith. 710038032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 710138032Speter CONFIG: change default version level from 4 to 5. 710238032Speter CONFIG: add FEATURE(nullclient) to create a config file that 710338032Speter forwards all mail to a hub without ever looking at the 710438032Speter addresses in any detail. 710538032Speter CONFIG: properly strip mailer: information off of relays when 710638032Speter used to change .BITNET form into %-hack form. 710738032Speter CONFIG: fix a problem that caused infinite loops if presented 710838032Speter with an address such as "!foo". 710938032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 711038032Speter the reverse "PTR" mapping is broken. There's a better 711138032Speter way to do this, but the change is fairly major and I 711238032Speter want to hold it for another release. Problem noted by 711338032Speter Bret Marquis. 711438032Speter 711564562Sgshapiro8.5/8.5 1993/07/23 711638032Speter Serious bug: if you used a command line recipient that was unknown 711738032Speter sendmail would not send a return message (it was treating 711838032Speter everything as though it had an SMTP-style client that 711938032Speter would do the return itself). Problem noted by Josh Smith. 712038032Speter Change "trymx" option in getcanonname() to ignore all MX data, 712138032Speter even during a T_ANY query. This actually didn't break 712238032Speter anything, because the only time you called getcanonname 712338032Speter with !trymx was if you already knew there were no MX 712438032Speter records, but it is somewhat cleaner. From Motonori 712538032Speter Nakamura. 712638032Speter Don't call getcanonname from getmxrr if you already know there 712738032Speter are no DNS records matching the name. 712838032Speter Fix a problem causing error messages to always include "The 712938032Speter original message was received ... from localhost". 713038032Speter The correct original host information is now included. 713138032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 713238032Speter version of "test" doesn't have the -x flag). Change it 713338032Speter to use -f instead. From John Myers. 713438032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 713538032Speter esmtp -- it should be smtp. 713638032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 713738032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 713838032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 713938032Speter this cleans up the configs somewhat. This fixes a serious 714038032Speter problem that caused route-addrs to get mistaken as relays, 714138032Speter pointed out by John Myers. WARNING: this also causes 714238032Speter the default on SMART_HOST to change from "suucp" to 714338032Speter "relay" if you have MAILER(smtp) specified. 714438032Speter 714564562Sgshapiro8.4/8.4 1993/07/22 714638032Speter Add option `w'. If you receive a message that comes to you because 714738032Speter you are the best (lowest preference) target of an MX, and 714838032Speter you haven't explicitly recognized the source MX host in 714938032Speter your .cf file, this option will cause you to try the target 715038032Speter host directly (as if there were no MX for it at all). If 715138032Speter `w' is not set, this case is a configuration error. 715238032Speter Beware: if `w' is set, senders may get bogus errors like 715338032Speter "message timed out" or "host unknown" for problems that 715438032Speter are really configuration errors. This option is 715538032Speter disrecommended, provided only for compatibility with 715638032Speter UIUC sendmail. 715738032Speter Fix a problem that caused the incoming socket to be left open 715838032Speter when sendmail forks after the DATA command. This caused 715938032Speter calling systems to wait in FIN_WAIT_2 state until the 716038032Speter entire list was processed and the child closed -- a 716138032Speter potentially prodigious amount of time. Problem noted 716238032Speter by Neil Rickert. 716338032Speter Fix problem (created in 6.64) that caused mail sent to multiple 716438032Speter addresses, one of which was a bad address, to completely 716538032Speter suppress the sending of the message. This changes 716638032Speter handling of EF_FATALERRS somewhat, and adds an 716738032Speter EF_GLOBALERRS flag. This also fixes a potential problem 716838032Speter with duplicate error messages if there is a syntax error 716938032Speter in the header of a message that isn't noticed until late 717038032Speter in processing. Original problem pointed out by Josh Smith 717138032Speter of Harvey Mudd College. This release includes quite a bit 717238032Speter of dickering with error handling (see below). 717338032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 717438032Speter will only hurt already-broken software and should help 717538032Speter humans. 717638032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 717738032Speter compiled in. It would never read the alias file. 717838032Speter Repair unbalanced `)' and `>' (the "open" versions are already 717938032Speter repaired). 718038032Speter Logging of "done" in dropenvelope() was incorrect: it would 718138032Speter log this even when the queue file still existed. Change 718238032Speter this to only log "done" (at log level 11) when the 718338032Speter queue file is actually removed. From John Myers. 718438032Speter Log "lost connection" in server SMTP at log level 20 if there 718538032Speter is no pending transaction. Some senders just close the 718638032Speter connection rather than sending QUIT. 718738032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 718838032Speter domains that do not have MX records -- this would cause 718938032Speter the subsequent host name lookup to fail. The problem 719038032Speter only occurred if you had FEATURE(nocanonify) set. 719138032Speter Problem noted by Rick McCarty of Texas Instruments. 719238032Speter Fix invocation of setvbuf when passed a -X flag -- I had 719338032Speter unwittingly used an ANSI C extension, and this caused 719438032Speter core dumps on some machines. 719538032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 719638032Speter Previously it just gave an empty send queue, which 719738032Speter then gave either "Need RCPT (recipient)" at the DATA 719838032Speter (confusing, since you had given an RCPT command which 719938032Speter returned 250) or just dropped the email, depending on 720038032Speter whether you were running VERBose mode. Now it usually 720138032Speter diagnoses this case as "aliasing/forwarding loop broken". 720238032Speter Unfortunately, it still doesn't adequately diagnose 720338032Speter some true error conditions. 720438032Speter Add internal concept of "warning messages" using 6xx codes. 720538032Speter These are not reported only to Postmaster. Unbalanced 720638032Speter parens, brackets, and quotes are printed as 653 codes. 720738032Speter They are always mapped to 5xx codes before use in SMTP. 720838032Speter Clean up error messages to tell both the actual address that 720938032Speter failed and the alias they arose from. This makes it 721038032Speter somewhat easier to diagnose problems. Difficulty noted 721138032Speter by Motonori Nakamura. 721238032Speter Fix a problem that inappropriately added a ctladdr to addresses 721338032Speter that shouldn't have had one during a queue run. This 721438032Speter caused error messages to be handled differently during 721538032Speter a queue run than a direct run. 721638032Speter Don't print the qf name and line number if you get errors during 721738032Speter the direct run of the queue from srvrsmtp -- this was 721838032Speter just extra stuff for users to crawl through. 721938032Speter Put command line flags on second line of pid file so you can 722038032Speter auto-restart the daemon with all appropriate arguments. 722138032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 722238032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 722338032Speter restart it. 722438032Speter Remove the ``setuid(getuid())'' in main -- this caused the 722538032Speter IDENT daemon to screw up. This required that I change 722638032Speter HASSETEUID to HASSETREUID and complicate the mode 722738032Speter changing somewhat because both Ultrix and SunOS seem 722838032Speter to have a bug causing seteuid() to set the saved uid 722938032Speter as well as the effective. The program test/t_setreuid.c 723038032Speter will test to see if your implementation of setreuid(2) 723138032Speter is appropriately functional. 723238032Speter The FallBackMX (option V) handling failed to properly identify 723338032Speter fallback to yourself -- most of the code was there, 723438032Speter but it wasn't being enabled. Problem noted by Murray 723538032Speter Kucherawy of the University of Waterloo. 723638032Speter Change :include: open timeout from ETIMEDOUT to an internal 723738032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 723838032Speter with CurHostName" in error messages, which can be 723938032Speter confusing. Reported by Jonathan Kamens of OpenVision 724038032Speter Technologies. 724138032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 724238032Speter process group id. The original fix was to get around 724338032Speter some problems with recalcitrant MUAs, but it breaks 724438032Speter any call from a shell that creates a process group id 724538032Speter different from the process id. I could try to fix 724638032Speter this by diddling the tty owner (using tcsetpgrp or 724738032Speter equivalent) but this is too likely to break other 724838032Speter things. 724938032Speter Portability changes: 725038032Speter Support -M as equivalent to -oM on Ultrix -- apparently 725138032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 725238032Speter instead of using standard flags. Oh joy. This 725343730Speter behavior reported by Jon Giltner of University 725438032Speter of Colorado. 725538032Speter SGI IRIX -- this includes several changes that should 725638032Speter help other strict ANSI compilers. 725738032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 725838032Speter Corporation. 725938032Speter Solaris running the Sun C compiler (which despite the 726038032Speter documentation apparently doesn't define 726138032Speter __STDC__ by default). 726238032Speter ConvexOS from Eric Schnoebelen of Convex. 726338032Speter Sony NEWS workstations and Omron LUNA workstations from 726438032Speter Motonori Nakamura. 726538032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 726638032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 726738032Speter several people have made a good argument that this 726838032Speter creates more problems than it solves (although this 726938032Speter may prove painful in the short run). 727038032Speter CONFIG: generalize all the relays to accept a "mailer:host" 727138032Speter format. 727238032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 727338032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 727438032Speter addresses are also passed through this ruleset. 727538032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 727638032Speter internet-style addresses would "fall off the end" of 727738032Speter ruleset zero and be interpreted as local -- however, 727838032Speter the angle brackets confused the recursive call. 727938032Speter These are now diagnosed as "Unrecognized host name". 728038032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 728138032Speter ifdef(`_MAILER_USENET_') instead of 728238032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 728338032Speter of SINTEF RUNIT, Oslo. 728438032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 728538032Speter early in ruleset 0; this allows .mc authors to bypass 728638032Speter things like the "short circuit" code for local addresses. 728738032Speter Prompted by a comment by Bill Wisner of The Well. 728838032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 728938032Speter esmtp) to send SMTP mail. This allows you to default 729038032Speter to esmtp but use a mailertable or other override to 729138032Speter deal with broken servers. This logic was pointed out 729238032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 729338032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 729438032Speter environments. Ugly as sin. 729538032Speter 729664562Sgshapiro8.3/8.3 1993/07/13 729738032Speter Fix setuid problems introduced in 8.2 that caused messages 729838032Speter like "Cannot create qfXXXXXX: Invalid argument" 729938032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 730038032Speter involved a new compile flag "HASSETEUID" that takes 730138032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 730238032Speter that the POSIX interface is broken enough to break 730338032Speter some systems badly. This includes some fixes for 730438032Speter HP-UX. Also fixes problems where the real uid is 730538032Speter not reset properly on startup (from Neil Rickert). 730638032Speter Fix a problem that caused timed out messages to not report the 730738032Speter addresses that timed out. Error messages are also more 730838032Speter "user friendly". 730938032Speter Drop required bandwidth on connections from 64 bytes/sec to 731038032Speter 16 bytes/sec. 731138032Speter Further Solaris portability changes -- doesn't require the BSD 731238032Speter compatibility library. This also adds a new 731338032Speter "HASGETDTABLESIZE" compile flag which can be used if 731438032Speter you want to use getdtablesize(2) instead of sysconf(2). 731538032Speter These are loosely based on changes from David Meyer at 731638032Speter University of Oregon. This now seems to work, at least 731738032Speter for quick test cases. 731838032Speter Fix a problem that can cause duplicate error messages to be 731938032Speter sent if you are in SMTP, you send to multiple addresses, 732038032Speter and at least one of those addresses is good and points 732138032Speter to an account that has a .forward file (whew!). 732238032Speter Fix a problem causing messages to be discarded if checkcompat() 732338032Speter returned EX_TEMPFAIL (because it didn't properly mark 732438032Speter the "to" address). Problem noted by John Myers. 732538032Speter Fix dfopen to return NULL if the open failed; I was depending 732638032Speter on fdopen(-1) returning NULL, which isn't the case. This 732738032Speter isn't serious, but does result in weird error diagnoses. 732838032Speter From Michael Corrigan. 732938032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 733038032Speter messages sent through UUCP-family mailers. Suggested 733138032Speter by Bill Wisner of The Well. 733238032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 733338032Speter include a "uucp-dom" mailer that uses domain-style 733438032Speter addressing. Suggested by Bill Wisner. 733538032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 733638032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 733738032Speter Christophe Wolfhugel. 733838032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 733938032Speter 734064562Sgshapiro8.2/8.2 1993/07/11 734138032Speter Don't drop out on config file parse errors in -bt mode. 734238032Speter On older configuration files, assume option "l" (use Errors-To 734338032Speter header) for back compatibility. NOTE: this DOES NOT 734438032Speter imply an endorsement of the Errors-To: header in any way. 734538032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 734638032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 734738032Speter SMTP server to give an error on this command, and 734838032Speter logging it in the transcript can be confusing. Fix 734938032Speter from Bill Wisner. 735038032Speter IRIX compatibility changes provided by Dan Rich 735138032Speter <drich@sandman.lerc.nasa.gov>. 735238032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 735338032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 735438032Speter <juo@klinzhai.rutgers.edu> 735538032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 735638032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 735738032Speter match the other flags in that file. 735838032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 735938032Speter Save h_errno in mci struct and improve error message display. 736038032Speter Changes from Eric Wassenaar. 736138032Speter Open /dev/null for the transcript if the create of the xf file 736238032Speter failed; this avoids at least one possible null pointer 736338032Speter reference in very weird cases. From Eric Wassenaar. 736438032Speter Clean up statistics gathering; it was over-reporting because of 736538032Speter forks. From Eric Wassenaar. 736638032Speter Fix problem that causes old Return-Path: line to override new 736738032Speter Return-Path: line (conf.c needs H_FORCE to avoid 736838032Speter re-using old value). From Motonori Nakamura. 736938032Speter Fix broken -m flag in K definition -- even if -m (match only) 737038032Speter was specified, it would still replace the key with the 737138032Speter value. Noted by Rick McCarty of Texas Instruments. 737238032Speter If the name server timed out over several days, no "timed out" 737338032Speter message would ever be sent back. The timeout code 737438032Speter has been moved from markfailure() to dropenvelope() 737538032Speter so that all such failures should be diagnosed. Pointed 737638032Speter out by Christophe Wolfhugel and others. 737738032Speter Relax safefile() constraints: directories in an include or 737838032Speter forward path must be readable by self if the controlling 737938032Speter user owns the entry, readable by all otherwise (e.g., 738038032Speter when reading your .forward file, you have to own and 738138032Speter have X permission in it; everyone needs X permission in 738238032Speter the root and directories leading up to your home); 738338032Speter include files must be readable by anyone, but need not 738438032Speter be owned by you. 738538032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 738638032Speter reading a .forward file; this gets around some problems 738738032Speter on NFS mounts if root permission is not exported and 738838032Speter the user's home directory isn't x'able. 738938032Speter Additional NeXT portability enhancements from Axel Zinser. 739038032Speter Additional HP-UX portability enhancements from Brian Bullen. 739138032Speter Add a timeout around SMTP message writes; this assumes you can 739238032Speter get throughput of at least 64 bytes/second. Note that 739338032Speter this does not impact the "datafinal" default, which 739438032Speter is separate; this is just intended to work around 739538032Speter network clogs that will occur before the final dot 739638032Speter is sent. From Eric Wassenaar. 739738032Speter Change map code to set the "include null" flag adaptively -- 739838032Speter it initially tries both, but if it finds anything 739938032Speter matching without a null it never tries again with a 740038032Speter null and vice versa. If -N is specified, it never 740138032Speter tries without the null and creates new maps with a 740238032Speter null byte. If -O is specified, it never tries with 740338032Speter the null (for efficiency). If -N and -O are specified, 740438032Speter you get -NO (get it?) lookup at all, so this would 740538032Speter be a bad idea. If you don't specify either -N or -O, 740638032Speter it adapts. 740738032Speter Fix recognition of "same from address" so that MH submissions 740838032Speter will insert the appropriate full name information; 740938032Speter this used to work and got broken somewhere along the 741038032Speter way. 741138032Speter Some changes to eliminate some unnecessary SYSERRs in the 741238032Speter log. For example, if you lost a connection, don't 741338032Speter bother reporting that fact on the connection you lost. 741438032Speter Add some "extended debugging" flags to try to track down 741538032Speter why we get occasional problems with file descriptor 741638032Speter one being closed when execing a mailer; it seems to 741738032Speter only happen when there has been another error in the 741838032Speter same transaction. This requires XDEBUG, defined 741938032Speter by default in conf.h. 742038032Speter Add "-X filename" command line flag, which logs both sides of 742138032Speter all SMTP transactions. This is intended ONLY for 742238032Speter debugging bad implementations of other mailers; start 742338032Speter it up, send a message from a mailer that is failing, 742438032Speter and then kill it off and examine the indicated log. 742538032Speter This output is not intended to be particularly human 742638032Speter readable. This also adds the HASSETVBUF compile 742738032Speter flag, defaulted on if your compiler defines __STDC__. 742838032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 742938032Speter have a local net that should get direct connects, you 743038032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 743138032Speter See cf/README for an example. 743238032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 743338032Speter sites that don't use the -d flag. 743438032Speter CONFIG: hide recipient addresses as well as sender addresses 743538032Speter behind $M if FEATURE(allmasquerade) is specified; this 743638032Speter has been requested by several people, but can break 743738032Speter local aliases. For example, if you mail to "localalias" 743838032Speter this will be rewritten as "localalias@masqueradehost"; 743938032Speter although initial delivery will work, replies will be 744038032Speter broken. Use it sparingly. 744138032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 744238032Speter to qualified domains in headers. I believe this is 744338032Speter largely equivalent to the IDA feature of the same name. 744438032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 744538032Speter to override the "system name" as your UUCP name -- 744638032Speter in particular, to use domain-ized UUCP names. From 744738032Speter Bill Wisner of The Well. 744838032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 744938032Speter first. This is currently unused in the config files, 745038032Speter but could be used in a mailertable entry. 745138032Speter 745264562Sgshapiro8.1C/8.1B 1993/06/27 745338032Speter Serious security bug fix: it was possible to read any file on 745438032Speter the system, regardless of ownership and permissions. 745538032Speter If a subroutine returns a fully qualified address, return it 745638032Speter immediately instead of feeding it back into rewriting. 745738032Speter This fixes a problem with mailertable lookups. 745838032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 745938032Speter 746064562Sgshapiro8.1B/8.1A 1993/06/12 746138032Speter Serious bug fix: pattern matching backup algorithm stepped by 746238032Speter two tokens in classes instead of one. Found by Claus 746338032Speter Assmann at University of Kiel, Germany. 746438032Speter 746564562Sgshapiro8.1A/8.1A 1993/06/08 746638032Speter Another mailertable fix.... 746738032Speter 746864562Sgshapiro8.1/8.1 1993/06/07 746938032Speter 4.4BSD freeze.
